Help¶

After enabling this option, the sleep period measurement is done using the same clock source as the active period, and one additional PPI channel is used. If you use the internal RC oscillator for at least one of the clock sources (high or low frequency), this option will ensure more accurate results. Enabling this option allows going to low power idle mode because the high frequency clock is not used by this module.
