Technical Data

Resets and interrupts are responses to exceptional events during
program execution. A reset re-initializes the MCU to its startup condition.
An interrupt vectors the program counter to a service routine.
A reset immediately returns the MCU to a known startup condition and
begins program execution from a user-defined memory location.
A reset:
A logic 0 applied to the RST pin for a time, t
reset. An external reset sets the PIN bit in the SIM reset status register.
