Part Number: AM2634


Tool/software:

Hi.

The r5fss0-0 kernel of the AM2634 chip has a reset of Watchdog 0. Why do I read the value 67 from the register shown below? It should be 66. Please tell me what does the value of this register equal to 67 mean?

    It could be because of the previous 0x41 value present (which is the reset value) and 0x42 gets added to this due to WDT0. Could you please try clearing the WARM_RST_CAUSE register (by writing 0x7 into WARM_RST_CAUSE_CLR) before reading this value?
