Setting the IDLE bit of PCON register invokes the IDLE mode. The IDLE mode leaves internal clocks and peripherals

running. Power consumption drops because the CPU is not active. The CPU can exit the IDLE state with any interrupts or

a reset.

exit this state only if interrupts asserted from external INT0/1, LVI and WDT interrupt, or hardware reset by WDT and

LVR.
