PCON
14 Power Management
14.1 Idle Mode
The user can enter the idle mode by setting the IDLE bit in the PCON register. In the idle mode, the
internal clock to the CPU part is stopped but the clock still remains for the peripherals and the
interrupt logic continues. The CPU part will exit idle mode when either an interrupt or a reset occurs.
14.2 Power down mode
When the PD bit in the PCON register is set, the CPU enters the power-down mode as idle mode
does. But the peripherals are also stopped. To exit from power down mode is done by a hardware
reset or external interrupts.
