 ************************* ESP32S2 Root Clock Source ****************************
 * 1) Internal 8MHz RC Oscillator: RC_FAST (usually referred as FOSC or CK8M/CLK8M in TRM and reg. description)
 *
 *    This RC oscillator generates a ~8.5MHz clock signal output as the RC_FAST_CLK.
 *    The ~8.5MHz signal output is also passed into a configurable divider, which by default divides the input clock
 *    frequency by 256, to generate a RC_FAST_D256_CLK (usually referred as 8md256 or simply d256 in reg. description).
 *
 *    The exact frequency of RC_FAST_CLK can be computed in runtime through calibration on the RC_FAST_D256_CLK.
 *
 * 2) External 40MHz Crystal Clock: XTAL
 *
 * 3) Internal 90kHz RC Oscillator: RC_SLOW (usually referred as RTC in TRM or reg. description)
 *
 *    This RC oscillator generates a ~90kHz clock signal output as the RC_SLOW_CLK. The exact frequency of this clock
 *    can be computed in runtime through calibration.
 *
 * 4) External 32kHz Crystal Clock (optional): XTAL32K
 *
 *    The clock source for this XTAL32K_CLK can be either a 32kHz crystal connecting to the XTAL_32K_P and XTAL_32K_N
 *    pins or a 32kHz clock signal generated by an external circuit. The external signal must be connected to the
 *    XTAL_32K_P pin.
 *
 *    XTAL32K_CLK can also be calibrated to get its exact frequency.
