| What is the watchdog timer reset? |
* Answer
| When the PM1 bit of the PM1 register is “1” (reset when the watchdog timer underflows), if the watchdog timer underflows, the microcontroller initializes the pin, CPU, and SFR, and then the address pointed to by the reset vector.Start executing the program.In the watchdog timer reset, some of the SFRs are not initialized. |
