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.
