	  Choose which clock is used as RTC clock source.

	  - "Internal 90kHz oscillator" option provides lowest deep sleep current
	    consumption, and does not require extra external components. However
	    frequency stability with respect to temperature is poor, so time may
	    drift in deep/light sleep modes.
	  - "External 32kHz crystal" provides better frequency stability, at the
	    expense of slightly higher (1uA) deep sleep current consumption.
	  - "External 32kHz oscillator" allows using 32kHz clock generated by an
	    external circuit. In this case, external clock signal must be connected
	    to 32K_XN pin. Amplitude should be <1.2V in case of sine wave signal,
	    and <1V in case of square wave signal. Common mode voltage should be
	    0.1 < Vcm < 0.5Vamp, where Vamp is the signal amplitude.
	    Additionally, 1nF capacitor must be connected between 32K_XP pin and
	    ground. 32K_XP pin can not be used as a GPIO in this case.
	  - "Internal 8MHz oscillator divided by 256" option results in higher
	    deep sleep current (by 5uA) but has better frequency stability than
	    the internal 90kHz oscillator. It does not require external components.

	help
	  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:

	  - 90000 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.

	  Configure the number of universally administered (by IEEE) MAC addresses.
	  During initialization, MAC addresses for each network interface are generated or
	  derived from a single base MAC address. If the number of universal MAC addresses is two,
	  all interfaces (WiFi station, WiFi softap) receive a universally administered MAC
	  address.
	  They are generated sequentially by adding 0, and 1 (respectively) to the final octet of
	  the base MAC address. If the number of universal MAC addresses is one, only WiFi station
	  receives a universally administered MAC address.
	  The WiFi softap receives local MAC addresses. It's derived from the universal WiFi
	  station MAC addresses.
	  When using the default (Espressif-assigned) base MAC address, either setting can be used.
	  When using a custom universal MAC address range, the correct setting will depend on the
	  allocation of MAC addresses in this range (either 1 or 2 per device).
