13.5 Idle Mode

The Idle mode is entered when the OSCCON[SLPEN] bit is low and the CPU executes a WFI instruction. Only the CPU’s internal clock is stopped in this mode.

Note: When exiting from the Sleep mode, the CRU will transition the system to the Idle mode before transitioning to the Run mode. This transition to the Idle mode is used to support the Dream mode and always occurs regardless of the CRU transitioning to the Dream mode or Run mode. Therefore, when exiting the Sleep mode, both the RCON bits [SLEEP] and [IDLE] will be set.
