Note 5-1-1: CKC= High:
a. If CKC=1,the phase lock loop (PLL) is adopted in the LCD module.
b. Inputs CSY, the controller of LCD module will separate the Vertical Sync and
Horizontal Sync from CSY.
c. Output Horizontal Sync ( HSY , Pin 1) and Vertical Sync ( VSY , Pin 14)..
d. The internal detect will detect Vertical Sync to reset the vertical counter.
