The value of this option determines the calibration interval of the RTC_FAST/SLOW clock during sleep when
power management is enabled. When it is configured as N, the RTC_FAST/SLOW clock will be calibrated
every N times of lightsleep.
Decreasing this value will increase the time the chip is in the active state, thereby increasing the
average power consumption of the chip.
Increasing this value can reduce the average power consumption, but when the external environment changes
drastically and the chip RTC_FAST/SLOW oscillator frequency drifts, it may cause system instability.
