What causes for the hardware reset operation to be out of control?

Latest Updated:02/27/2012

Question:

Hardware reset operation is not normal (out of control). What is the cause?

Answer:

First, check whether the program has jumped to the address indicated by the reset vector.
If the program has not jumped to the address, check if the reset is input as specified.
If the program runs out of control after it has jumped to the address, check the stack pointer and interrupt table settings. The watchdog timer also automatically starts when bit 0 of address FFFFFh in the flash memory is set to 0. Check the value of address FFFFFh.
