S12XECRG performs a quality check on the incoming clock signal. As soon as clock quality check
indicates a valid Oscillator Clock signal the reset sequence starts using the Oscillator clock. If after 50
check windows the clock quality check indicated a non-valid Oscillator Clock the reset sequence starts
using Self-Clock Mode.
