8-bit OTP Type IO Controller
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 for FPP0 is 0x000. The interrupt entry is 0x010 if used, the last eight addresses are reserved for
system using, like checksum, serial number, etc. The OTP program memory for PMC150/PMS150 is a 1KW
that is partitioned as Table 1. The OTP memory from address 0x3F8 to 0x3FF is for system using, address
space from 0x001 to 0x00F and from 0x011 to 0x3F7 are user program space.

5.2. Boot Up
POR (Power-On-Reset) is used to reset PMC150/PMS150 when power up, however, the supply voltage may
be not stable. To ensure the stability of supply voltage after power up, it will wait 1024 ILRC clock cycles
before first instruction being executed, which is tSBP and shown in the Fig. 1.

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. All the 60 bytes data memory of PMC150/PMS150 can be accessed by indirect access mechanism.
5.4. Oscillator and clock
There are two oscillator circuits provided by PMC150/PMS150: internal high RC oscillator (IHRC) and internal
low RC oscillator (ILRC), and these two oscillators are enabled or disabled by registers clkmd.4 and clkmd.2
independently. User can choose one of these two oscillators as system clock source and use clkmd register
to target the desired frequency as system clock to meet different application.

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. The frequency deviation can
be within 2% normally after calibration and it still drifts slightly with supply voltage and operating temperature.
Please refer to the measurement chart for IHRC frequency verse VDD and IHRC frequency verse
temperature.
The frequency of ILRC is around 37KHz, however, its 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. IHRC calibration
The IHRC frequency may be different chip by chip due to manufacturing variation, PMC150/PMS150
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=2.2 ~ 5.5; In order to calibrate the chip under different supply voltage.

5.5. 16-bit Timer (Timer16)
PMC150/PMS150 provide a 16-bit hardware timer (Timer16) and its clock source may come from system
clock (CLK), internal high RC oscillator (IHRC), internal low RC oscillator (ILRC), PA0 or PA4. Before sending
clock to the 16-bit counter, a pre-scaling logic with divided-by-1, 4, 16 or 64 is selectable for wide range
counting. The 16-bit counter performs up-counting operation only, the counter initial values can be stored
from data memory by issuing the stt16 instruction and the counting values can be loaded to data memory by
issuing the ldt16 instruction. The interrupt request from Timer16 will be triggered by the selected bit which
comes from bit[15:8] of this 16-bit counter, rising edge or falling edge can be optional chosen by register
integs.4. The hardware diagram of Timer16 is shown as Fig. 3.

When using the Timer16, the syntax for Timer16 has been defined in the .INC file. There are three
parameters to define the Timer16 using; 1st parameter is used to define the clock source of Timer16, 2nd
parameter is used to define the pre-scalar and the 3rd one is to define the interrupt source.

5.6. Watchdog Timer
The watchdog timer (WDT) is a counter with clock coming from ILRC and its frequency is about 37KHz@5V.
There are four different timeout periods of watchdog timer can be chosen by setting the misc register, it is:
256 ILRC clock period when misc[1:0]=11
16384 ILRC clock period when misc[1:0]=10
4096 ILRC clock period when misc[1:0]=01
2048 ILRC clock period when misc[1:0]=00 (default)
The frequency of ILRC may drift a lot due to the variation of manufacture, supply voltage and temperature;
user should reserve guard band for safe operation. WDT can be cleared by power-on-reset or by command
wdreset at any time. When WDT is timeout, PMC150 will be reset to restart the program execution. The
relative timing diagram of watchdog timer is shown as Fig. 4.

5.7. Interrupt
There are two interrupt lines for PMC150/PMS150:
External interrupt PA0
Timer16 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. 5. 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.

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.
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. For interrupt operation, the following sample program shows how to handle the
interrupt, noticing that it needs four bytes stack memory to handle interrupt and pushaf.

5.8. 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 3 shows the differences in oscillator modules between Power-Save mode
(“stopexe”) and Power-Down mode (“stopsys”).

Table 3: Differences in oscillator modules between STOPSYS and STOPEXE
5.8.1. Power-Save mode (“stopexe”)
Using “stopexe” instruction to enter the Power-Save mode, only system clock is disabled, remaining all the
oscillator modules be active. For CPU, it stops executing; however, for Timer16, counter keep counting if its
clock source is not the system clock. The wake-up sources for “stopexe” can be IO-toggle or Timer16
counts to set values when the clock source of Timer16 is IHRC or ILRC modules. Wake-up from input pins
can be considered as a continuation of normal execution, nop command is recommended to follow the
stopexe command, the detail information for Power-Save mode shown below:
IHRC 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
Timer16: Stop counting if system clock is selected or the corresponding oscillator module is disabled;
otherwise, it keeps counting.
Wake-up sources: IO toggle in digital mode (PxDIER bit is 1) or Timer16.
The watchdog timer must be disabled before issuing the “stopexe” command, the example is shown as
below:
CLKMD.En_WatchDog
=
0;
// disable watchdog timer
stopexe;
nop;
….
// power saving
Wdreset;
CLKMD.En_WatchDog
=
1;
// enable watchdog timer
Another example shows how to use Timer16 to wake-up from “stopexe”:
$ T16M IHRC, /1, BIT8
…
// Timer16 setting
WORD
STT16
stopexe;
nop;
count
count;
=
0;
…
The initial counting value of Timer16 is zero and the system will be waken up after the Timer16 counts 256
IHRC clocks.

IO-Type Controller
5.8.2. 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. The internal low frequency RC
oscillator must be enabled before entering the Power-Down mode, means that bit 2 of register clkmd (0x03)
must be set to high before issuing “stopsys” command in order to resume the system when wakeup. The
following shows the internal status of PMC150/PMS150 in detail when “stopsys” command is issued:
All the oscillator modules are turned off
Enable internal low RC oscillator (set bit 2 of register clkmd)
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:
CMKMD
=
0xF4;
0;
//
//
Change clock from IHRC to ILRC, disable watchdog timer
disable IHRC
CLKMD.4 =
…
while (1)
{
STOPSYS;
if (…) break;
//
//
//
enter power-down
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

5.8.3. Wake-up
After entering the Power-Down or Power-Save modes, the PMC150/PMS150 can be resumed to normal
operation by toggling IO pins, Timer16 interrupt is available for Power-Save mode ONLY. Table 4 shows the
differences in wake-up sources between STOPSYS and STOPEXE.

Table 3: Differences in wake-up sources between Power-Save mode and Power-Down mode
When using the IO pins to wake-up the PMC150/PMS150, registers padier should be properly set to enable
the wake-up function for every corresponding pin. The wake-up time for normal wake-up is about 1024 ILRC
clocks counting from wake-up event; fast wake-up can be selected to reduce the wake-up time by misc
register. For fast wake-up mechanism, the wake-up time is 128 system clocks from IO toggling if STOPEXE
was issued, and 128 system clocks plus IHRC oscillator stable time from IO toggling if STOPSYS was
issued. The oscillator stable time is the time for IHRC oscillator from power-on.

5.9. IO Pins
Other than PA5, all the pins can be independently set into two states output or input by configuring the data
registers (pa), control registers (pac) and pull-high registers (paph). 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 5 shows the configuration table of bit 0 of port A. The
hardware diagram of IO buffer is also shown as Fig. 6.

Other than PA5, all the IO pins have the same structure; PA5 can be open-drain ONLY when setting to output
mode (without Q1). When PMC150/PMS150 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 to high. The same reason, padier.0 should be
set to high when PA0 is used as external interrupt pin.

5.10. Reset and LVR
5.10.1. Reset
There are many causes to reset the PMC150/PMS150, once reset is asserted, all the registers in
PMC150/PMS150 will be set to default values, system should be restarted once abnormal cases happen, or
by jumping program counter to address ’h0. 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 PRST# pin or WDT timeout.
5.10.2. LVR reset
By code option, there are many different levels of LVR for reset. Usually, user selects LVR reset level to be in
conjunction with operating frequency and supply voltage.
5.10.3. Notice for LVR reset
In some applications, the power VDD may change rapidly because of quick switching the power source
manually or strong power noise. In case, when the power VDD drops to the level that is lower than the LVR
level but higher than 1.0V, if at this time the power VDD is pulled up again to be over LVR level (just see the
diagram below), there may be some chances that cause the MCU malfunction or hanged.

To avoid the above problem, please follow the below steps in your program:
Step 1. Insert the below two instructions just after the .ADJUST_IC instruction
SET1
Notice: IDE 0.57 or above version will insert this instruction automatically.
Intrq 0;
inten.7
=
Notice: IDE 0.59 or above version will insert this instruction automatically.
Step 2. Never clear the inten.7 through out the whole program. Please pay special attention in accidental clear
inten.7 by writing operation to the whole inten register. Please consider using set1/set0 instruction to
change other interrupt enable flags.
Notice: IDE 0.57 or above version will block the reset operation of inten.7 automatically.
Step 3. When wdreset instruction is being used:
Please modify the wdreset instruction inside the main loop of the program:
C language:
If (inten.7==0) reset; else {wdreset;}
Assembly language:
t1sn
inten.7;
reset
wdreset
or use as below :
.wdreset
(for IDE 0.57 or above version only)
Step 4. When clkmd is being used:
When clkmd instruction is set inside the main loop of the program and clkmd.1 = 0, please insert below
instructions afterward.
C language:
If (inten.7==0) reset;
Assembly language:
t1sn
inten.7;
reset
or use as below to set clkmd:
.clkmd = 0x hh;
( “hh” is a hexadecimal value. For IDE 0.59 or above version only)

9. Special Notes
This chapter is to remind user who use PMC150/PMS150 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 as 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) If IO pin is set to be digital input and enable wake-up function
Configure IO pin as input
Set corresponding bit to “1” in PADIER
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 PRST# input pin
No internal pull-high resistor for PA5
Configure PA5 as input
Set CLKMD.0=1 to enable PA5 as PRST# 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 >10Ω resistor in between PA5 and the long wire
Avoid using PA5 as input in such application.
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
©Copyright 2018, PADAUK Technology Co. Ltd
Page 53 of 56
PDK-DS-PMX150-EN-V108 – Dec. 11, 2018
PMC150/PMS150 Series
IO-Type Controller
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. Power down mode, wakeup and watchdog
(1) Watchdog will be inactive once ILRC is disabled
(2) Please turn off watchdog before executing STOPSYS or STOPEXE instruction, otherwise IC will be reset
due to watchdog timeout. It is the same as in ICE emulation.
(3) The clock source of Watchdog is ILRC if the fast wakeup is disabled; otherwise, the clock source of
Watchdog will be the system clock and the reset time from watchdog becomes much shorter. It is
recommended to disable Watchdog and enable fast wakeup before entering STOPSYS mode. When the
system is waken up from power down mode, please firstly disable fast wakeup function, and then enable
Watchdog. It is to avoid system to be reset after being waken up.
(4) If enable Watchdog during programming and also wants the fast wakeup, the example as below:
CLKMD.En_WatchDog
=
0;
// disable watchdog timer
$ MISC
stopexe;
nop;
Fast_Wake_Up;

IO-Type Controller
$ MISC
WT_xx;
// Reset Watchdog time to normal wake-up
// enable watchdog timer
Wdreset;
CLKMD.En_WatchDog
=
1;
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. LVR
(1) VDD must reach or above 2.0V for successful power-on process; otherwise IC will be inactive.
(2) The setting of LVR (1.8V, 2.0V, 2.2V etc) will be valid just after successful power-on process.
(3) User can set EOSCR.0 as “1” to disable LVR. However, VDD must be kept as exceeding the lowest
working voltage of chip; Otherwise IC may work abnormally.
9.2.7. IHRC
(1) The IHRC frequency calibration is performed when IC is programmed by the writer.
(2) 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.
(3) It usually happens in COB package or Quick Turnover Programming (QTP). And PADAUK would not take
any responsibility for this situation.
(4) 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.

9.2.8. Program writing
There are 6 pins for using the writer to program: PA3, PA4, PA5, PA6, VDD and GND.
Please use PDK3S-P-002 for program real chip and just use the CN38 jumper (at the back for the writer)
with putting the PMC150/PMS150-S08/DIP8 IC downward three 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).
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 circuit or
components will not be destroyed or limit the above voltages.
