12.1. Idle mode
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.
12.2. Stop mode
Setting the STOP bit of PCON register invokes the STOP mode. All internal clocking in this mode is turn off. The CPU will
exit this state only if interrupts asserted from external INT0/1, KBI, LVI, and RTC, or a hardware reset by WDT and LVR.
