<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
