Resets and Interrupts
8.1 Introduction
Reset initializes the MCU by returning the program counter to a known address and by forcing control and
status bits to known states.
Interrupts temporarily change the sequence of program execution to respond to events that occur during
processing.
8.2 Resets
A reset immediately stops the operation of the instruction being executed, initializes certain control and
status bits, and loads the program counter with a user-defined reset vector address. The following
sources can generate a reset:
Power-on reset (POR) circuit
RESET pin
Computer operating properly (COP) watchdog
Illegal address
