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.

Note 5-1-2: CKC= Low (VGA mode)
a. If CKC=0, the phase lock loop (PLL) is not adopted in the LCD module.
b. If CKC=0, the external clock input frequency of Pin 3 is 25.175 MHz.
c. Input external Horizontal Sync (Pin 1) to synchronize the LCD module. External
Horizontal Sync and External Vertical Sync input pulse can be high going or low
going.
0. The cycle of external Horizontal Sync input is 31.8µs. The cycle of external Vertical
Sync input is 525H.
