6.3.1 Usage of Ports 5~7 Input Change Wake-up/Interrupt Function

1. Wake-up

a) Before Sleep:

1) Disable WDT

2) Read I/O Port (MOV R6,R6)

3) Execute "ENI" or "DISI"

4) Enable Wake-up bit (Set ICWKPx = 1)

5) Execute "SLEP" instruction

b) After Wake-up:

 Next instruction

2. Wake-up and Interrupt

a) Before SLEEP
