Hello, How reliable is the data flash (using FSP VEE module) in case of interrupting power supply during write/erase operation?

While writing a little Program in Assembly language we are having a strange problem by configuring the Timer or the Analog Measurement.
Two simple examples. We want to set the analog input P103:
LDR r0, =0x0008
LDR r1, =ADANSA1
STRH r0, [r1]
But nothing happens. ADANSA1 still contains zeros. Or I wanted to start the Timer 164
LDR r0, =0x0001
LDR r1, =GTCR164
STRH r0, [r1]
Also, in this case the GTCR164 still contains only zeros. I can’t find a reason why accessing the registers doesn’t work. For the timer register I have also checked that the write protection is disabled.
Can it have something to do with the setting of the peripheral clock?
We have set the clock to HOCO 32 MHz and the clock architecture to type. Regarding the divisor we have set 8 for all clock, so actually we should have the same clock of 4 MHz.

You have to enable the GPT and/or ADC in the “Module Stop Control Register D".

Hi, However, it seems that if 2 consecutive power interrupts during write operations occur, the data aren't copied again after the second power interrupt, If I understand your concern right. So the VEEPROM has no valid data in this case. I hope it helps. Thank You
