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 64 bytes data memory of PMC156/PMS156 can be accessed by indirect access mechanism.
5.4. Oscillator and clock
There are three oscillator circuits provided by PMC156/PMS156: 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. 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 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, PMC156/PMS156 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=16 ~ 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.

5.4.4. 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.

Besides crystal, external capacitor and options of PMC156 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.

Table 4: Recommend values of C1 and C2 for crystal and resonator oscillators
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:

...
Please notice that the crystal oscillator should be fully turned off before entering the power-down mode, in
order to avoid unexpected wakeup event. If the 32kHz crystal oscillator is used and extremely low operating
current is required, misc.6 can be set to reduce current after crystal oscillator is running normally.

5.4.6. System Clock Switching
After IHRC calibration, user may want to switch system clock to a new frequency or may switch system clock at
any time to optimize the system performance and power consumption. Basically, the system clock of PMC156
can be switched among IHRC, ILRC and EOSC by setting the clkmd register at any time; system clock will be
the new one after writing to clkmd register immediately. Please notice that the original clock module can NOT
be turned off at the same time as writing command to clkmd register. The examples are shown as below and
more information about clock switching, please refer to the “Help -> Application Note -> “IC introduction” ->
“ Register introduction” -> “CLKMD”.

5.5 16-bit Timer (Timer16)
A 16-bit hardware timer (Timer16) is implemented in the PMC156/PMS156, 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) 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. 4. 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 4 of integs register (IO address 0x0C).

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.

User can choose the proper parameters of T16M to meet system requirement, examples as below (For more
examples, please refer to IDE software "Application Note Introduction of IC Introduction of Register
T16M"):
$
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.

5.6 Watchdog Timer
The watchdog timer (WDT) is a counter with clock coming from ILRC. There are three different timeout periods
of watchdog timer can be chosen by setting the misc register, they are:
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, PMC156 will be reset to restart the program execution. The relative timing
diagram of watchdog timer is shown as Fig. 5.

5.7 Interrupt
There are three interrupt lines for PMC156:
External interrupt PA0
External interrupt PB0
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. 6. 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. Fig. 7 shows the differences in oscillator modules between Power-Save mode (“stopexe”) and
Power-Down mode (“stopsys”).

Fig. 7: 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 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 the
set values when clock sources of Timer16 come from IHRC, ILRC or EOSC 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 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
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;
1;
// disable watchdog timer
stopexe;
nop;
….
// power saving
Wdreset;
CLKMD.En_WatchDog
// enable watchdog timer

PMC156/PMS156 Series

Another example shows how to use Timer16 to wake-up from “stopexe”:
$ T16M IHRC, /1, BIT8
…
// Timer16 setting
WORD
STT16
stopexe;
nop;
count
=
0;
count;
…
The initial counting value of Timer16 is zero and the system will be waken up after the Timer16 counts 256 IHRC
clocks.
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 PMC156 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
CLKMD.4
…
=
=
0xF4;
0;
//
//
change clock from IHRC to ILRC, disable watchdog timer
disable IHRC
while (1)
{
STOPSYS;
//
//
//
enter power-down
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

5.8.3. Wake-up
After entering the Power-Down or Power-Save modes, the PMC156 can be resumed to normal operation by
toggling IO pins, Timer16 interrupt is available for Power-Save mode ONLY. Fig. 8 shows the differences in
wake-up sources between STOPSYS and STOPEXE.

Fig. 8: Differences in wake-up sources between Power-Save mode and Power-Down mode
When using the IO pins to wake-up the PMC156/PMS156, registers padier and pbdier 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 oscillator (IHRC or ILRC) stable time from IO toggling if
STOPSYS was issued. The oscillator stable time is the time for IHRC or ILRC oscillator from power-on,
depending on which oscillator is used as system clock source. Please notice that there is no fast wake-up
mode whenever EOSC is enabled.

Please notice that the clock source of watch-dog will be switched to system clock (for example: 4MHz) when

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, pb), control registers (pac, pbc) and pull-high registers (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 5 shows the configuration table of bit 0 of port A.
The hardware diagram of IO buffer is also shown as Fig. 9.

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 PMC156 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 or pbdier to high. The same reason, padier.0 should
be set high when PA0 is used as external interrupt pin and pbdier.0 for PB0.

5.10 Reset and LVR
5.10.1. Reset
There are many causes to reset the PMC156/PMS156, once reset is asserted, all the registers in PMC156
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.

9. Special Notes
This chapter is to remind user who use PMC153/PMS153 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
(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.
(5) 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

8bit OTP Type 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
(1) 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.
Case 1 : 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
Case 2 : Switch system clock from ILRC to EOSC
CLKMD
=
0xA6;
0;
// switch to EOSC, 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
=
(2) Please ensure the EOSC oscillation has established before switching from ILRC or IHRC to EOSC. MCU
will not check its status. Please wait for a while after enabling EOSC. System clock can be switched to
EOSC afterwards. Otherwise, MCU will hang. The example for switching system clock from ILRC to 4MHz
EOSC after boot up is as below:

The delay duration should be adjusted in accordance with the characteristic of the crystal and PCB.To
measure the oscillator signal by the oscilloscope, please select (x10) on the probe and measure through
PA6(X2) pin to avoid the interference on the oscillator.
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;
$ MISC
Wdreset;
WT_xx;
// Reset Watchdog time to normal wake-up
// enable watchdog timer
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. LCD COM pin application
(1) There are two groups of LCD COM IO selectable for PMC156/PMS156, they are
PA_1234(PA1/COM1,PA2/COM2,PA3/COM3,PA4/COM4) and
PB_1256(PB1/COM0A,PB2/COM1A,PB5/COM2A,PB6/COM3A).
(2) In the practical application, only one group is actually used. User can select one of the groups in Code
Option where the LVR value is also selectable before program compiling. The code option is shown as
below. Please notice that once the code option is confirmed, any change will be unacceptable in the next
programming.

9.2.9. 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 CN40 jumper (at the back for the writer) with
putting the PMC156/PMS156- SOP14/16/20 & SOP18/DIP18 IC in the top of 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)
(2)
(3)
PA5 (VPP) may be higher than 11V.
DD may be higher than 6.5V, and its maximum current may reach about 20mA.
All other signal pins level (except GND) are the same as VDD.
V
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.
9.3. Using ICE
Please use PDK5S-I-S01/2(B) ICE to emulate PMC156/PMS156. Please note in the simulation:
PDK5S-I-S01/2(B) doesn’t support the instruction NMOV/SWAP/NADD/COMP with RAM
PDK5S-I-S01/2(B) doesn’t support the dynamic setting of function misc.4 (Only fix to 0 or 1)
Fast Wakeup time is different from PDK5S-I-S01/2(B): 128 SYSCLK, PMC156/PMS156: refer to 5.8.3
Watch dog time out period is different from PDK5S-I-S01/2(B):
WDT period
misc[1:0]=00
misc[1:0]=01
misc[1:0]=10
misc[1:0]=11
