            This setting defines which hardware timers are used to
            implement 'gettimeofday' and 'time' functions in C library.

            - If both high-resolution (systimer) and RTC timers are used, timekeeping will
              continue in deep sleep. Time will be reported at 1 microsecond
              resolution. This is the default, and the recommended option.
            - If only high-resolution timer (systimer) is used, gettimeofday will
              provide time at microsecond resolution.
              Time will not be preserved when going into deep sleep mode.
            - If only RTC timer is used, timekeeping will continue in
              deep sleep, but time will be measured at 6.(6) microsecond
              resolution. Also the gettimeofday function itself may take
              longer to run.
            - If no timers are used, gettimeofday and time functions
              return -1 and set errno to ENOSYS.
            - When RTC is used for timekeeping, two RTC_STORE registers are
              used to keep time in deep sleep mode.

            When the startup code initializes RTC_SLOW_CLK, it can perform
            calibration by comparing the RTC_SLOW_CLK frequency with main XTAL
            frequency. 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.
