Power-saving modes

The device provides two power saving modes of operation for applications where power consumption is critical. The two modes are idle and Power-down.

Idle mode

Idle mode is entered setting the IDL bit in the PCON register. In idle mode, the program counter (PC) is stopped. The system clock continues to run and all interrupts and peripherals remain active. The on-chip RAM and the special function registers hold their data during this mode.
