Idle Mode

When IDLEN is set (IDLEN = 1), the SLEEP instruction will put the device into Idle mode. In Idle mode, the CPU and memory operations are halted, but the peripheral clocks continue to run. This mode is similar to Doze mode, except that in IDLE both the CPU and PFM are shut off.

Important: If CLKOUTEN is enabled (CLKOUTEN = 0, Configuration Word 1H), the output will continue operating while in Idle.
