KEY ON WAKE UP
“Key on wake up” is one way of returning from a power down state
caused by the STP or WIT instruction. If any terminal of port P0
has “L” level applied, after bit 5 of the edge polarity selection regis-
ter (EG5) is set to “1”, an interrupt is generated and the
microcomputer is returned to the normal operating state. A key
matrix can be connected to port P0 and the microcomputer can be
returned to a normal state by pushing any key.
The key on wake up interrupt is common with the INT1 interrupt.
When EG5 is set to “1”, the key on wake up function is selected.
However, key on wake up cannot be used in the normal operating
state. When the microcomputer is in the normal operating state,
both key on wake up and INT1 are invalid.
