9.3. Using ICE

(1)

PDK5S-I-S01/2(B) supports PFS123 MCU emulation, the following items should be noted when using

PDK5S-I-S01/2(B) to emulate PFS123:



PDK5S-I-S01/2(B) doesn’t support the instruction NMOV/SWAP/NADD/COMP with RAM.



PDK5S-I-S01/2(B) doesn’t support SYSCLK=ILRC/16.



PDK5S-I-S01/2(B) doesn’t support the dynamic setting of function misc.4 (Only fix to 0 or 1)



PDK5S-I-S01/2(B) doesn’t support the function Tm2.gpcrs/Tm3.gpcrs.



PDK5S-I-S01/2(B) doesn’t support band-gap reference voltage for ADC channel F of ADCRGC [3:2].

Only 1.2V exists and is fixed.



PDK5S-I-S01/2(B) doesn’t support the code options: PB4_PB5_Drive, GPC_PWM, TMx_source,

PWM_Source and TMx_bit.



PDK5S-I-S01/2(B) doesn’t support SuLED PWM generation and related registers.



PDK5S-I-S01/2(B) doesn’t support VDD/2 function of PB0.



PDK5S-I-S01/2(B) has different setting of PC2 and PC1 in adcc.



PDK5S-I-S01/2(B) only supports 240 bytes RAM for data memory.



The PCDIER register of the PDK5S-I-S01/2(B) emulator is different from the real chip. The PCDIER[0]

of the PDK5S-I-S01/2(B) is used to set PC0~PC3 to be digital input whereas PCDIER[1] is used to

set PC4~ PC7 to be digital input. It is recommended not to set PCDIER.



When using PB1 in ADCRGC, PA1 must float.



When using GPCC output, PA3 will be influenced.



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, PFS123: 45 ILRC



Watch dog time out period is different from PDK5S-I-S01/2(B):

WDT period
