(*1) <Frame frequency Calculation at external clock mode>
DISCTL 80Hz setting : Frame frequency [Hz] = external clock [Hz] / 512
DISCTL 71Hz setting : Frame frequency [Hz] = external clock [Hz] / 576
DISCTL 64Hz setting : Frame frequency [Hz] = external clock [Hz] / 648
DISCTL 53Hz setting : Frame frequency [Hz] = external clock [Hz] / 768
