CONFIG_CPU_LOAD_ALIGNED_CLOCKS

Enable aligned clock sources

Type: bool

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.
