This option sets the number of RTC_SLOW_CLK cycles measured by the calibration routine. Higher numbers increase calibration precision, which may be important for applications which spend a lot of time in deep sleep. Lower numbers reduce startup time. When this option is set to 0, clock calibration will not be performed at startup, and approximate clock frequencies will be assumed: - 150000 Hz if internal RC oscillator is used as clock source. For this use value 1024. - 32768 Hz if the 32k crystal oscillator is used. For this use value 3000 or more. In case more value will help improve the definition of the launch of the crystal. If the crystal could not start, it will be switched to internal RC. endmenu endif # SOC_FAMILY_ESPRESSIF_ESP32
