CHAPTER 24 RESET FUNCTION
24.4.4 Operation immediately after reset ends
(1) Immediately after reset ends normally
Immediately after a reset ends, the main clock starts oscillating, the oscillation stabilization time (which differs
depending on the option byte; for details, see CHAPTER 29 OPTION BYTE) is secured, and then the CPU
starts executing the program.
WDT2 begins to operate immediately after a reset ends using the internal oscillator clock as the source clock.
