The following three functions: reset, STOP and WAIT, are not in the strictest sense interrupts. However,
they are acted upon in a similar manner. Flowcharts for STOP and WAIT are shown in
RESET: A reset condition causes the program to vector to its starting address, which is contained

in memory locations $3FFE (MSB) and $3FFF (LSB). The I-bit in the condition code
register is also set, to disable interrupts.
in SLEEP mode, it causes the oscillator to be turned off until an external, WOI or CIRQ
interrupt occurs or the device is reset.
running. This ‘rest’ state of the processor can be cleared by reset, an external or WOI
interrupt, a timer interrupt or an SCI interrupt. There are no special WAIT vectors for
these individual interrupts.
The STOP instruction puts the processor to ‘sleep’ and, if the MCAN module is already
The WAIT instruction causes all processor clocks to stop, but leaves the timer clocks
