Resets and Interrupts
5.2 Introduction
5.3 Sources of Resets
Technical Data
106
NOTE:
When a reset or interrupt occurs, the microcontroller (MCU) retrieves the
starting address of a program or interrupt routine from a vector table in
memory and loads it in the program counter. A reset immediately stops
execution of the current instruction and reinitializes the control registers.
An interrupt preserves the current program status, performs an interrupt
service routine, and resumes operation as if there had been no
interruption.
The four sources of reset are:
Power-on reset and external reset share the same interrupt vectors.
The CPU fetches a restart vector during the first three clock cycles after
reset and begins executing instructions. Vector selection is based on the
type of reset and operating mode, as shown in
