Note : The modulation clock stabilization wait time is required after the power is turned on, the IC recovers from

power saving, or after FREQ (frequency range) or ENS (modulation ON/OFF) setting is changed. For the

modulation clock stabilization wait time, assign the maximum value for lock-up time.
