An interrupt temporarily changes the sequence of program execution to
respond to a particular event. An interrupt does not stop the operation of
the instruction being executed, but begins when the current instruction
completes its operation.
An interrupt:
•
1 = External reset via RST pin since last read of SRSR
0 = POR or read of SRSR since last external reset
1 = Last reset caused by timeout of COP counter
0 = POR or read of SRSR
1 = Last reset caused by an illegal opcode
0 = POR or read of SRSR
1 = Last reset caused by an opcode fetch from an illegal address
0 = POR or read of SRSR
1 = Last reset caused by monitor mode entry when vector locations
0 = POR or read of SRSR
1 = Last reset caused by low-power supply voltage
0 = POR or read of SRSR
Saves the CPU registers on the stack. At the end of the interrupt,
the RTI instruction recovers the CPU registers from the stack so
that normal processing can resume.
