The PMS152 family is an IO-Type, fully static, OTP-based CMOS 8-bit microcontroller. It employs RISC
architecture and all the instructions are executed in one cycle except that some instructions are two cycles that
handle indirect memory access.
1.25KW bits OTP program memory and 80 bytes data SRAM are inside, one hardware comparator is built inside
the chip to compare signal between two pin or with either internal reference voltage VinternalR or internal band-gap
reference voltage. PMS152 also provides three hardware timers: one 16-bit timer, one 8-bit timer with PWM
generation, and one new triple 11-bit timer with SuLED PWM generation (PWMG0, PWMG1 & PWMG2) are
included.

5. Functional Description
5.1. Program Memory - OTP
The OTP (One Time Programmable) program memory is used to store the program instructions to be executed.
The OTP program memory may contains the data, tables and interrupt entry. After reset, the initial address
0x000 is reserved for system using, so the program will start from 0x001 which is GOTO FPPA0 instruction
usually. The interrupt entry is 0x10 if used, the last 16 addresses are reserved for system using, like checksum,
serial number, etc. The OTP program memory for PMS152 is 1.25KW that is partitioned as Table 1. The OTP
memory from address ‘0x4E6 to 0x4FF is for system using, address space from0x002 to 0x00F and from
0x011 to 0x4E5 are user program spaces.

5.2. Boot Procedure
POR (Power-On-Reset) is used to reset PMS152 when power up. The boot up time can be optional fast or
normal. Time for fast boot-up is about 47 ILRC clock cycles whereas 2945 ILRC clock cycles for normal
boot-up. Customer must ensure the stability of supply voltage after power up no matter which option is chosen,
the power up sequence is shown in the Fig. 1 and tSBP is the boot up time.
Please noted, during Power-On-Reset, the VDD must go higher than VPOR to boot-up the MCU.

5.3. Data Memory - SRAM
The access of data memory can be byte or bit operation. Besides data storage, the SRAM data memory is also
served as data pointer of indirect access method and the stack memory.
The stack memory is defined in the data memory. The stack pointer is defined in the stack pointer register; the
depth of stack memory of each processing unit is defined by the user. The arrangement of stack memory fully
flexible and can be dynamically adjusted by the user.
For indirect memory access mechanism, the data memory is used as the data pointer to address the data byte.
All the data memory could be the data pointer; it’s quite flexible and useful to do the indirect memory access.
Since the data width is 8-bit, all the 80 bytes data memory of PMS152 can be accessed by indirect access
mechanism.
5.4. Oscillator and Clock
There are three oscillator circuits provided by PMS152: external crystal oscillator (EOSC), internal high RC
oscillator (IHRC) and internal low RC oscillator (ILRC), and these three oscillators are enabled or disabled by
registers eoscr.7, clkmd.4 and clkmd.2 independently. User can choose one of these three oscillators as
system clock source and use clkmd register to target the desired frequency as system clock to meet different
applications.

5.4.1. Internal High RC oscillator and Internal Low RC oscillator
After boot-up, the IHRC and ILRC oscillators are enabled. The frequency of IHRC can be calibrated to
eliminate process variation by ihrcr register; normally it is calibrated to 16MHz. Please refer to the
measurement chart for IHRC frequency verse VDD and IHRC frequency verse temperature.
The frequency will vary by process, supply voltage and temperature, please refer to DC specification and do
not use for accurate timing application.
5.4.2. Chip calibration
The IHRC frequency and band-gap reference voltage may be different chip by chip due to manufacturing
variation, PMS152 provide the IHRC frequency calibration to eliminate this variation, and this function can be
selected when compiling user’s program and the command will be inserted into user’s program automatically.
The calibration command is shown as below:
.ADJUST_IC SYSCLK=IHRC/(p1), IHRC=(p2)MHz, VDD=(p3)V;
Where, p1=2, 4, 8, 16, 32; In order to provide different system clock.
p2=14 ~ 18; In order to calibrate the chip to different frequency, 16MHz is the usually one.
p3=1.8 ~ 5.5; In order to calibrate the chip under different supply voltage.

Table 3: Options for IHRC Frequency Calibration
Usually, .ADJUST_IC will be the first command after boot up, in order to set the target operating frequency
whenever starting the system. The program code for IHRC frequency calibration is executed only one time that
occurs in writing the codes into OTP memory; after then, it will not be executed again. If the different option for
IHRC calibration is chosen, the system status is also different after boot. The following shows the status of
PMS152 for different option:
(1) .ADJUST_IC
SYSCLK=IHRC/2, IHRC=16MHz, VDD=5V

5.4.4. External Crystal Oscillator
If crystal oscillator is used, a crystal or resonator is required between X1 and X2. Fig.2 shows the hardware
connection under this application; the range of operating frequency of crystal oscillator can be from 32 KHz to
4MHz, depending on the crystal placed on; higher frequency oscillator than 4MHz is NOT supported.

The values of C1 and C2 should depend on
the specification of crystal.
Fig.2: Connection of crystal oscillator
Besides crystal, external capacitor and options of PMS152 should be fine tuned in eoscr (0x0a) register to
have good sinusoidal waveform. The eoscr.7 is used to enable crystal oscillator module, eoscr.6 and eoscr.5
are used to set the different driving current to meet the requirement of different frequency of crystal oscillator:
eoscr.[6:5]=01 : Low driving capability, for lower frequency, ex: 32KHz crystal oscillator
eoscr.[6:5]=10 : Middle driving capability, for middle frequency, ex: 1MHz crystal oscillator
eoscr.[6:5]=11 : High driving capability, for higher frequency, ex: 4MHz crystal oscillator
Table 4 shows the recommended values of C1 and C2 for different crystal oscillator; the measured start-up
time under its corresponding conditions is also shown. Since the crystal or resonator had its own characteristic,
the capacitors and start-up time may be slightly different for different type of crystal or resonator, please refer to
its specification for proper values of C1 and C2.

When using the crystal oscillator, user must pay attention to the stable time of oscillator after enabling it, the
stable time of oscillator will depend on frequency “crystal type” external capacitor and supply voltage. Before
switching the system to the crystal oscillator, user must make sure the oscillator is stable; the reference
program is shown as below:
void
{
FPPA0 (void)
. ADJUST_IC SYSCLK=IHRC/16, IHRC=16MHz, VDD=5V
$ EOSCR

}
Please notice that the crystal oscillator should be fully turned off before entering the power-down mode, in
order to avoid unexpected wake-up event.

5.5. Comparator
One hardware comparator is built inside the PMS152; Fig.4 shows its hardware diagram. It can compare
signals between two pins or with either internal reference voltage Vinternal R or internal band-gap reference
voltage. The two signals to be compared, one is the plus input and the other one is the minus input. For the
minus input of comparator can be PA3, PA4, Internal band-gap 1.20 volt, PB6, PB7 or Vinternal R selected by bit
[3:1] of gpcc register, and the plus input of comparator can be PA4 or Vinternal R selected by bit 0 of gpcc register.
The output result can be enabled to output to PA0 directly, or sampled by Time2 clock (TM2_CLK) which
comes from Timer2 module. The output can be also inversed the polarity by bit 4 of gpcc register, the
comparator output can be used to request interrupt service.

Using the comparator
Case I:
Choosing PA3 as minus input and Vinternal R with (18/32)*VDD voltage level as plus input. Vinternal R is
configured as the above Figure “gpcs[5:4] = 2b’00” and gpcs [3:0] = 4b’1001 (n=9) to have Vinternal R
(1/4)*VDD + [(9+1)/32]*VDD = [(9+9)/32]*VDD = (18/32)*VDD.
=
gpcs = 0b1_0_00_1001;
gpcc = 0b1_0_0_0_000_0;

// - input: N_xx,+ input: P_R(Vinternal R
)
PADIER = 0bxxxx_0_xxx;
Case 2:
Choosing Vinternal R as minus input with (22/40)*VDD voltage level and PA4 as plus input, the comparator
result will be inversed and then output to PA0. Vinternal R is configured as the above Figure “gpcs[5:4] =
2b’10” and gpcs [3:0] = 4b’1101 (n=13) to have Vinternal R = (1/5)*VDD + [(13+1)/40]*VDD = [(13+9)/40]*VDD
(22/40)*VDD.
=
gpcs = 0b1_0_10_1101;
gpcc = 0b1_0_0_1_011_1;
padier = 0bxxx_0_xxxx;
// output to PA0, Vinternal R = VDD*(22/40)

Note: When selecting output to PA0 output, GPCS will affect the PA3 output function in ICE. Though the IC
is fine, be careful to avoid this error during emulation.

5.5.3 Using the comparator and band-gap 1.20V
The internal band-gap module can provide 1.20 volt, it can measure the external supply voltage level. The
band-gap 1.20 volt is selected as minus input of comparator and Vinternal R is selected as plus input, the
supply voltage of Vinternal R is VDD, the VDD voltage level can be detected by adjusting the voltage level of
Vinternal R to compare with band-gap. If N (gpcs[3:0] in decimal) is the number to let Vinternal R closest to
band-gap 1.20 volt, the supply voltage VDD can be calculated by using the following equations:
For using Case 1: VDD = [ 32 / (N+9) ] * 1.20 volt ;
For using Case 2: VDD = [ 24 / (N+1) ] * 1.20 volt ;
For using Case 3: VDD = [ 40 / (N+9) ] * 1.20 volt ;
For using Case 4: VDD= [ 32 / (N+1) ] * 1.20 volt ;
Case 1:
$ GPCS VDD*12/40;
// 4.0V * 12/40 = 1.2V

5.6 16-bit Timer (Timer16)
A 16-bit hardware timer (Timer16) is implemented in the PMS152, the clock sources of Timer16 may come
from system clock (CLK), clock of external crystal oscillator (EOSC), internal high RC oscillator (IHRC),
internal low RC oscillator (ILRC), PA4 and PA0, a multiplex is used to select clock output for the clock source.
Before sending clock to the counter16, a pre-scaling logic with divided-by-1, 4, 16, and 64 is used for wide
range counting. The 16-bit counter performs up-counting operation only, the counter initial values can be
stored from memory by stt16 instruction and the counting values can be loaded to memory by ldt16 instruction.
A selector is used to select the interrupt condition of Timer16, whenever overflow occurs, the Timer16 interrupt
can be triggered. The hardware diagram of Timer16 is shown as Fig.9. The interrupt source of Timer16 comes
from one of bit 8 to 15 of 16-bit counter, and the interrupt type can be rising edge trigger or falling edge trigger
which is specified in the bit 5 of integs register (address 0x0C).
PA4
Fig.9: Hardware diagram of Timer16
When using the Timer16, the syntax for Timer16 has been defined in the .INC file. There are three parameters
to define the Timer16; 1st parameter is used to define the clock source of Timer16, 2nd parameter is used to
define the pre-scalar and the last one is to define the interrupt source. The detail description is shown as
below:

User can define the parameters of T16M based on system requirement, some examples are shown below and
more examples please refer to “Help Application Note IC Introduction Register Introduction T16M” in
IDE utility.
$ T16M SYSCLK, /64, BIT15;
// choose (SYSCLK/64) as clock source, every 2^16 clock to set INTRQ.2=1
// if using System Clock = IHRC / 2 = 8 MHz
// SYSCLK/64 = 8 MHz/64 = 125KHz, about every 512 mS to generate INTRQ.2=1
$ T16M EOSC, /1, BIT13;
// choose (EOSC/1) as clock source, every 2^14 clocks to generate INTRQ.2=1
// if EOSC=32768 Hz, 32768 Hz/(2^14) = 2Hz, every 0.5S to generate INTRQ.2=1
$ T16M PA0_F, /1, BIT8;
// choose PA0 as clock source, every 2^9 to generate INTRQ.2=1
// receiving every 512 times PA0 to generate INTRQ.2=1
$ T16M STOP;
// stop Timer16 counting
If Timer16 is operated at free running, the frequency of interrupt can be described as below:
FINTRQ_T16M = Fclock source ÷ P ÷ 2n+1
Where, F is the frequency of selected clock source to Timer16;
P is the selection of t16m [4:3]; (1, 4, 16, 64)
N is the nth bit selected to request interrupt service, for example: n=10 if bit 10 is selected.

5.7 8-bit Timer (Timer2) with PWM generation
An 8-bit hardware timer (Timer2) with PWM generation is implemented in the PMS152. Please refer to Fig.10
shown the hardware diagram of Timer2, the clock sources of Timer2 may come from system clock, internal high
RC oscillator (IHRC), internal low RC oscillator (ILRC), external crystal oscillator (EOSC), PA0, PB0, PA4 and
comparator. Bit [7:4] of register tm2c are used to select the clock of Timer2. If IHRC is selected for Timer2 clock
source, the clock sent to Timer2 will keep running when using ICE in halt state. The output of Timer2 can be
sent to pin PB2, PA3 or PB4, depending on bit [3:2] of tm2c register. A clock pre-scaling module is provided with
divided-by- 1, 4, 16, and 64 options, controlled by bit [6:5] of tm2s register; one scaling module with
divided-by-1~31 is also provided and controlled by bit [4:0] of tm2s register. In conjunction of pre-scaling
function and scaling function, the frequency of Timer2 clock (TM2_CLK) can be wide range and flexible.
The Timer2 counter performs 8-bit up-counting operation only; the counter values can be set or read back by
tm2ct register. The 8-bit counter will be clear to zero automatically when its values reach for upper bound
register in period mode. The upper bound register is used to define the period of timer or duty of PWM. There
are two operating modes for Timer2: period mode and PWM mode; period mode is used to generate periodical
output waveform or interrupt event; PWM mode is used to generate PWM output waveform with optional 6-bit,
7-bit or 8-bit PWM resolution, Fig.11 shows the timing diagram of Timer2 for both period mode and PWM mode.

5.7.1 Using the Timer2 to generate periodical waveform
If periodical mode is selected, the duty cycle of output is always 50%; its frequency can be summarized as
below:
Frequency of Output = Y ÷ [2 × (K+1) × S1 × (S2+1) ]
Where,
Y = tm2c[7:4] : frequency of selected clock source
K = tm2b[7:0] : bound register in decimal
S1 = tm2s[6:5] : pre-scalar (S1=1, 4, 16, 64)
S2 = tm2s[4:0] : scalar register in decimal (S2=0 ~ 31)
Example 1:
tm2c = 0b0001_1000, Y=8MHz
tm2b = 0b0111_1111, K=127
tm2s = 0b0000_00000, S1=1, S2=0

5.7.2 Using the Timer2 to generate 8-bit PWM waveform
If 8-bit PWM mode is selected, it should set tm2c[1]=1 and tm2s[7]=0, the frequency and duty cycle of
output waveform can be summarized as below:
Frequency of Output = Y ÷ [256 × S1 × (S2+1) ]
Duty of Output = [( K+1 ) ÷ 256]×100%
Where, Y = tm2c[7:4] : frequency of selected clock source
K = tm2b[7:0] : bound register in decimal
S1= tm2s[6:5] : pre-scalar (S1=1, 4, 16, 64)
S2 = tm2s[4:0] : scalar register in decimal (S2=0 ~ 31)
Example 1:
tm2c = 0b0001_1010, Y=8MHz
tm2b = 0b0111_1111, K=127
tm2s = 0b0000_00000, S1=1, S2=0
frequency of output = 8MHz ÷ ( 256 × 1 × (0+1) ) = 31.25KHz
duty of output = [(127+1) ÷ 256] × 100% = 50%
Example 2:
tm2c = 0b0001_1010, Y=8MHz
tm2b = 0b0111_1111, K=127
tm2s = 0b0111_11111, S1=64, S2=31
frequency of output = 8MHz ÷ ( 256 × 64 × (31+1) ) = 15.25Hz
duty of output = [(127+1) ÷ 256] × 100% = 50%
Example 3:

tm2c = 0b0001_10_1_0;
while(1)
{
nop;
}
}
5.7.3 Using the Timer2 to generate 6-bit PWM waveform
If 6-bit PWM mode is selected, it should set tm2c[1]=1 and tm2s[7]=1, the frequency and duty cycle of
output waveform can be summarized as below:
Frequency of Output = Y ÷ [64 × S1 × (S2+1) ]
Duty of Output = [( K+1 ) ÷ 64] × 100%
Where, tm2c[7:4] = Y : frequency of selected clock source
tm2b[7:0] = K : bound register in decimal
tm2s[6:5] = S1 : pre-scalar (S1=1, 4, 16, 64)
tm2s[4:0] = S2 : scalar register in decimal (S2=0 ~ 31)
Users can set Timer2 to be 7-bit PWM mode instead of 6-bit mode by using TM2_Bit code option. At that
time, the calculation factors of the above equations become 128 instead of 64.
Example 1:
tm2c = 0b0001_1010, Y=8MHz
tm2b = 0b0001_1111, K=31
tm2s = 0b1000_00000, S1=1, S2=0
frequency of output = 8MHz ÷ ( 64 × 1 × (0+1) ) = 125KHz
duty = [(31+1) ÷ 64] × 100% = 50%
Example 2:
tm2c = 0b0001_1010, Y=8MHz
tm2b = 0b0001_1111, K=31
tm2s = 0b1111_11111, S1=64, S2=31
frequency of output = 8MHz ÷ ( 64 × 64 × (31+1) ) = 61.03 Hz
duty of output = [(31+1) ÷ 64] × 100% = 50%

5.8 11-bit PWM Generators
One set of triple 11-bit SuLED (Super LED) hardware PWM generator is implemented in the PMS152. It consists
of three PWM generators (PWMG0, PWMG1 & PWMG2). Their individual outputs are listed as below:
PWMG0 – PA0, PB4, PB5
PWMG1 – PA4, PB6, PB7
PWMG2 – PA3, PB2, PB3, PA5 (open drain output only)
Note: PDK5S-I-S01/2(B) doesn’t support the function of the set of 11-bit SuLED hardware PWM generators.
5.8.1 PWM Waveform
A PWM output waveform (Fig.13) has a time-base (TPeriod = Time of Period) and a time with output high
level (Duty Cycle). The frequency of the PWM output is the inverse of the period (fPWM = 1/TPeriod).

5.8.2 Hardware Diagram
Fig.14 shows the hardware diagram of the whole set of SuLED 11-bit hardware PWM generators. Those
three PWM generators use a common Up-Counter and clock source selector to create the time base, and
so the start points (the rising edge) of the PWM cycle are synchronized. The clock source can be IHRC or
system clock. The PWM signal output pins that can be selected via pwmgxc register selection. The period
of PWM waveform is defined by the common PWM upper bound high and low registers, and the duty cycle
of individual PWM waveform is defined by the individual set in the PWM duty high and low registers.
The additional OR and XOR logic of PWMG0 channel is used to create the complementary switching
waveforms with dead zone control. Selecting code option GPC_PWM can also control the generated
PWM waveform by the comparator result.

5.8.4 PWM Waveforms with Complementary Dead Zones
Based on the specific 11 bit PWM architecture of PMS152, here we employ PWM2 output and PWM0 inverse
output after PWM0 xor PWM1 to generate two PWM waveforms with complementary dead zones.
Example program is as follows:
#define dead_zone
#define PWM_Pulse

50
//
//
dead time = 10% * (1/PWM_Frequency) us
set 50% as PWM duty cycle

5.9 WatchDog Timer
The watchdog timer (WDT) is a counter with clock coming from ILRC. WDT can be cleared by power-on-reset
or by command wdreset at any time. There are four different timeout periods of watchdog timer to be chosen
by setting the misc register, it is:
8k ILRC clocks period if register misc[1:0]=00 (default)
16k ILRC clocks period if register misc[1:0]=01
64k ILRC clocks period if register misc[1:0]=10
256k ILRC clocks period if register misc[1:0]=11
The frequency of ILRC may drift a lot due to the variation of manufacture, supply voltage and temperature; user
should reserve guard band for save operation. Besides, the watchdog period will also be shorter than expected
after Reset or Wakeup events. It is suggested to clear WDT by wdreset command after these events to ensure
enough clock periods before WDT timeout.
When WDT is timeout, PMS152 will be reset to restart the program execution. The relative timing diagram of
watchdog timer is shown as Fig.18.

5.10. Interrupt
There are eight interrupt lines for PMS152:
External interrupt PA0/PB5
External interrupt PB0/PA4
Timer16 interrupt
GPC interrupt
PWMG interrupt
Timer2 interrupt
Every interrupt request line has its own corresponding interrupt control bit to enable or disable it; the hardware
diagram of interrupt function is shown as Fig.19. All the interrupt request flags are set by hardware and cleared
by writing intrq register. When the request flags are set, it can be rising edge, falling edge or both, depending
on the setting of register integs. All the interrupt request lines are also controlled by engint instruction (enable
global interrupt) to enable interrupt operation and disgint instruction (disable global interrupt) to disable it.
The stack memory for interrupt is shared with data memory and its address is specified by stack register sp.
Since the program counter is 16 bits width, the bit 0 of stack register sp should be kept 0. Moreover, user can
use pushaf / popaf instructions to store or restore the values of ACC and flag register to / from stack memory.
Since the stack memory is shared with data memory, the stack position and level are arranged by the compiler
in Mini-C project. When defining the stack level in ASM project, users should arrange their locations carefully to
prevent address conflicts.
Fig.19: Hardware diagram of interrupt controller
Once the interrupt occurs, its operation will be:
The program counter will be stored automatically to the stack memory specified by register sp.
New sp will be updated to sp+2.
Global interrupt will be disabled automatically.
The next instruction will be fetched from address 0x010.

PMS152
8bit OTP Type SuLED IO Controller
During the interrupt service routine, the interrupt source can be determined by reading the intrq register.
Note: Even if INTEN=0, INTRQ will be still triggered by the interrupt source.
After finishing the interrupt service routine and issuing the reti instruction to return back, its operation will be:
The program counter will be restored automatically from the stack memory specified by register sp.
New sp will be updated to sp-2.
Global interrupt will be enabled automatically.
The next instruction will be the original one before interrupt.
User must reserve enough stack memory for interrupt, two bytes stack memory for one level interrupt and four
bytes for two levels interrupt. And so on, two bytes stack memory is for pushaf. For interrupt operation, the
following sample program shows how to handle the interrupt, noticing that it needs four bytes stack memory to
handle one level interrupt and pushaf.

5.11. Power-Save and Power-Down
There are three operational modes defined by hardware: ON mode, Power-Save mode and Power-Down
modes. ON mode is the state of normal operation with all functions ON, Power-Save mode (“stopexe”) is the
state to reduce operating current and CPU keeps ready to continue, Power-Down mode (“stopsys”) is used to
save power deeply. Therefore, Power-Save mode is used in the system which needs low operating power with
wake-up occasionally and Power-Down mode is used in the system which needs power down deeply with
seldom wake-up. Table 5 shows the differences in oscillator modules between Power-Save mode (“stopexe”)
and Power-Down mode (“stopsys”).

Table 5: Differences in oscillator modules between STOPSYS and STOPEXE
5.11.1 Power-Save mode (“stopexe”)
Using “stopexe” instruction to enter the Power-Save mode, only system clock is disabled, remaining all
the oscillator modules active. For CPU, it stops executing; however, for Timer16, counter keep counting
if its clock source is not the system clock. Wake-up from input pins can be considered as a continuation
of normal execution, the detail information for Power-Save mode shows below:
IHRC and EOSC oscillator modules: No change, keep active if it was enabled.
ILRC oscillator modules: must remain enabled, need to start with ILRC when be wakening up.
System clock: Disable, therefore, CPU stops execution.
OTP memory is turned off.
Timer counter: Stop counting if its clock source is system clock or the corresponding oscillator module is
disabled; otherwise, it keeps counting. (The Timer contains TM16, TM2, PWMG0, PWMG1, PWMG2.)
Wake-up sources:
a. IO toggle wake-up: IO toggling in digital input mode (PxC bit is 1 and PxDIER bit is 1)
b. Timer wake-up: If the clock source of Timer is not the SYSCLK, the system will be awakened when
the Timer counter reaches the set value.
c. Comparator wake-up: It need setting GPCC.7=1 and GPCS.6=1 to enable the comparator wake-up
function at the same time.
An example shows how to use Timer16 to wake-up from “stopexe”:
$ T16M

stopexe;
…
The initial counting value of Timer16 is zero and the system will be woken up after the Timer16 counts 256
ILRC clocks.
5.11.2 Power-Down mode (“stopsys”)
Power-Down mode is the state of deeply power-saving with turning off all the oscillator modules. By using
the “stopsys” instruction, this chip will be put on Power-Down mode directly. It is recommend to set
GPCC.7=0 to disable the comparator before the command “stopsys”. The following shows the internal
status of PMS152 detail when “stopsys” command is issued:
All the oscillator modules are turned off.
OTP memory is turned off.
The contents of SRAM and registers remain unchanged.
Wake-up sources: IO toggle in digital mode (PxDIER bit is 1)
Wake-up from input pins can be considered as a continuation of normal execution. To minimize power
consumption, all the I/O pins should be carefully manipulated before entering power-down mode. The
reference sample program for power down is shown as below:
CLKMD
CLKMD.4
…
=
=
0xF4;
0;
//
//
Change clock from IHRC to ILRC

if (…) break;
if wakeup happen and check OK, then return to high speed,
else stay in power-down mode again
}
CLKMD
=
0x34;
//
Change clock from ILRC to IHRC/2
5.11.3 Wake-up
After entering the Power-Down or Power-Save modes, the PMS152 can be resumed to normal operation
by toggling IO pins. Wake-up from timer are available for Power-Save mode ONLY. Table 6 shows the
differences in wake-up sources between STOPSYS and STOPEXE.

When using the IO pins to wake-up the PMS152, registers pxdier should be properly set to enable the
wake-up function for every corresponding pin. The time for normal wake-up is about 3000 ILRC clocks
counting from wake-up event; fast wake-up can be selected to reduce the wake-up time by misc register,
and the time for fast wake-up is about 45 ILRC clocks from IO toggling.

5.12 IO Pins
All the pins can be independently set into two states output or input by configuring the data registers (pa, pb),
control registers (pac, pbc) and pull-high resistor (paph, pbph). All these pins have Schmitt-trigger input
buffer and output driver with CMOS level. When it is set to output low, the pull-high resistor is turned off
automatically. If user wants to read the pin state, please notice that it should be set to input mode before
reading the data port; if user reads the data port when it is set to output mode, the reading data comes from
data register, NOT from IO pad. As an example, Table 8 shows the configuration table of bit 0 of port A. The
hardware diagram of IO buffer is also shown as Fig.20.

Other than PA5, all the IO pins have the same structure; PA5 can be open-drain ONLY when setting to output
mode (without Q1). The corresponding bits in registers padier / pbdier should be set to low to prevent leakage
current for those pins are selected to be analog function. When PMS152 is put in power-down or power-save
mode, every pin can be used to wake-up system by toggling its state. Therefore, those pins needed to
wake-up system must be set to input mode and set the corresponding bits of registers padier and pbdier to
high. The same reason, padier.0 should be set high when PA0 is used as external interrupt pin, pbdier.0 for
PB0, padier.4 for PA4 and pbdier.5 for PB5.

5.13 Reset and LVR
5.13.1 Reset
There are many causes to reset the PMS152, once reset is asserted, most of all the registers in PMS152
will be set to default values, system should be restarted once abnormal cases happen, or by jumping
program counter to address 0x0. The data memory is in uncertain state when reset comes from power-up
and LVR; however, the content will be kept when reset comes from PRSTB pin or WDT timeout.
5.13.2 LVR reset
By code option, there are 8 different levels of LVR for reset ~ 4.5V, 3.5V, 3.0V, 2.7V, 2.5V, 2.2V, 2.0V and
1.8V; usually, user selects LVR reset level to be in conjunction with operating frequency and supply voltage.

9. Special Notes
This chapter is to remind user who use PMS152 series IC in order to avoid frequent errors upon operation.
9.1. Warning
User must read all application notes of the IC by detail before using it. Please download the related application
notes from the following link:
http://www.padauk.com.tw/tw/technical/index.aspx
9.2. Using IC
9.2.1. IO pin usage and setting
(1) IO pin is set to be digital input
When IO is set as digital input, the level of Vih and Vil would changes with the voltage and temperature.
Please follow the minimum value of Vih and the maximum value of Vil.
The value of internal pull high resistor would also changes with the voltage, temperature and pin voltage.
It is not the fixed value.
(2) IO pin as digital input and enable wakeup function
Configure IO pin as input
Set corresponding bit to “1” in PXDIER
For those IO pins of PA that are not used, PADIER[1:2] should be set low in order to prevent them from
leakage.
(3) PA5 is set to be output pin
PA5 can be set to be Open-Drain output pin only, output high requires adding pull-high resistor.
(4) PA5 is set to be PRSTB input pin
Configure PA5 as input
Set CLKMD.0=1 to enable PA5 as PRSTB input pin
(5) PA5 is set to be input pin and to connect with a push button or a switch by a long wire
Needs to put a >33Ω resistor in between PA5 and the long wire
Avoid using PA5 as input in such application.
(6) PA7 and PA6 as external crystal oscillator
Configure PA7 and PA6 as input
Disable PA7 and PA6 internal pull-high resistor
Configure PADIER register to set PA6 and PA7 as analog input
EOSCR register bit [6:5] selects corresponding crystal oscillator frequency :
01 : for lower frequency, ex : 32KHz
10 : for middle frequency, ex : 455KHz, 1MHz
11 : for higher frequency, ex : 4MHz
Program EOSCR.7 =1 to enable crystal oscillator
Ensure EOSC working well before switching from IHRC or ILRC to EOSC.

PMS152
8bit OTP Type SuLED IO Controller
Note: Please read the PMC-APN013 carefully. According to PMC-APN013, the crystal oscillator should be
used reasonably. If the following situations happen to cause IC start-up slowly or non-startup, PADAUK
Technology is not responsible for this: the quality of the user's crystal oscillator is not good, the usage
conditions are unreasonable, the PCB cleaner leakage current, or the PCB layouts are unreasonable.
9.2.2. Interrupt
(1) When using the interrupt function, the procedure should be:
Step1: Set INTEN register, enable the interrupt control bit
Step2: Clear INTRQ register
Step3: In the main program, using ENGINT to enable CPU interrupt function
Step4: Wait for interrupt. When interrupt occurs, enter to Interrupt Service Routine
Step5: After the Interrupt Service Routine being executed, return to the main program
*Use DISGINT in the main program to disable all interrupts
*When interrupt service routine starts, use PUSHAF instruction to save ALU and FLAG register.
POPAF instruction is to restore ALU and FLAG register before RETI as below:
void Interrupt (void)
// Once the interrupt occurs, jump to interrupt service routine
// enter DISGINT status automatically, no more interrupt is
{
accepted
PUSHAF;
…
POPAF;
}
// RETI will be added automatically. After RETI being executed, ENGINT status
will be restored
(2) INTEN and INTRQ have no initial values. Please set required value before enabling interrupt function.
9.2.3. System clock switching
System clock can be switched by CLKMD register. Please notice that, NEVER switch the system clock and
turn off the original clock source at the same time. For example: When switching from clock A to clock B,
please switch to clock B first; and after that turn off the clock A oscillator through CLKMD.
Example : Switch system clock from ILRC to IHRC/2
CLKMD
=
0x36;
0;
// switch to IHRC, ILRC can not be disabled here
CLKMD.2 =
// ILRC can be disabled at this time
ERROR: Switch ILRC to IHRC and turn off ILRC simultaneously
CLKMD 0x50; // MCU will hang
=
9.2.4. Watchdog
Watchdog will be inactive once ILRC is disabled.

9.2.5. TIMER time out
When select $ INTEGS BIT_R (default value) and T16M counter BIT8 to generate interrupt, if T16M counts
from 0, the first interrupt will occur when the counter reaches to 0x100 (BIT8 from 0 to 1) and the second
interrupt will occur when the counter reaches 0x300 (BIT8 from 0 to 1). Therefore, selecting BIT8 as 1 to
generate interrupt means that the interrupt occurs every 512 counts. Please notice that if T16M counter is
restarted, the next interrupt will occur once Bit8 turns from 0 to 1.
If select $ INTEGS BIT_F(BIT triggers from 1 to 0) and T16M counter BIT8 to generate interrupt, the T16M
counter changes to an interrupt every 0x200/0x400/0x600/. Please pay attention to two differences with
setting INTEGS methods.
9.2.6. IHRC
(1)
The IHRC frequency calibration is performed when IC is programmed by the writer.
Because the characteristic of the Epoxy Molding Compound (EMC) would some degrees affects the
IHRC frequency (either for package or COB), if the calibration is done before molding process, the
actual IHRC frequency after molding may be deviated or becomes out of spec. Normally , the
frequency is getting slower a bit.
(2)
(3)
(4)
It usually happens in COB package or Quick Turnover Programming (QTP). And PADAUK would not
take any responsibility for this situation.
Users can make some compensatory adjustments according to their own experiences. For example,
users can set IHRC frequency to be 0.5% ~ 1% higher and aim to get better re-targeting after molding.
9.2.7. LVR
User can set MISC.2 as “1” to disable LVR. However, VDD must be kept as exceeding the lowest working
voltage of chip; Otherwise IC may work abnormally.
9.2.8. Programming Writing
There are 6 pins for using the writer to program: PA3, PA4, PA5, PA6, VDD and GND.
If use PDK3S-P-002 to program PMS152 real chip, just use the CN39 jumper (at the back for the writer) with
putting the 16pin package IC on the top of the Textool. For the 14pin package, it need downward one space
on the Textool, for the 10pin package, it need downward three spaces on the Textool, and for the 8pin
package, it need downward four spaces on the Textool.
Other packages could be programmed by connecting the signals correspondingly. All the signals of the left
side of the jumpers are the same and as the descriptions at the left bottom corner. They are VDD, PA0(not
used), PA3, PA4, PA5, PA6, PA7(not used), and GND).

PMS152
8bit OTP Type SuLED IO Controller
If user use PDK5S-P-003 or above to program, please follow the instructions for connecting jumpers.
Special notes about voltage and current while Multi-Chip-Package(MCP) or On-Board Programming
(1) PA5 (VPP) may be higher than 11V.
(2)
VDD may be higher than 6.5V, and its maximum current may reach about 20mA.
(3) All other signal pins level (except GND) are the same as VDD.
User should confirm when using this product in MCP or On-Board Programming, the peripheral components
or circuit will not be damaged by the above voltages, and will not clam the above voltages.
Important Cautions:
You MUST follow the instructions on APN004 and APN011 for programming IC on the handler.
Connecting a 0.01uF capacitor between VDD and GND at the handler port to the IC is always
good for suppressing disturbance. But please DO NOT connect with >0.01uF capacitor,
otherwise, programming may be fail.

9.3. Using ICE
PDK5S-I-S01/2 (B) supports PMS152 1-FPPA MCU emulation work, the following items should be noted when
using PDK5S-I-S01/2(B) to emulate PMS152:
PDK5S-I-S01/2(B) doesn’t support the function of the set of 11-bit SuLED hardware PWM generators.
PDK5S-I-S01/2(B) doesn’t support the instruction NADD/COMP of PMS152.
PDK5S-I-S01/2 (B) doesn’t support SYSCLK=ILRC/16 of PMS152.
PDK5S-I-S01/2 (B) doesn’t support the function Tm2.gpcrs of PMS152.
The PA3 output function will be affected when GPCS selects output to PA0 output.
When simulating PWM waveform, please check the waveform during program running. When the ICE is
suspended or single-step running, its waveform may be inconsistent with the reality.
The ILRC frequency of the PDK5S-I-S01/2(B) simulator is different from the actual IC and is
uncalibrated, with a frequency range of about 34K~38KHz.
Fast Wakeup time is different from PDK5S-I-S01/2(B): 128 SysClk, PMS152: 45 ILRC.
Watch dog time out period is different from PDK5S-I-S01/2:
WDT period
misc[1:0]=00
misc[1:0]=01
misc[1:0]=10
misc[1:0]=11
