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 Synch from CSY.
c. Out put Horizontal Sync (HSY , Pin 1) and Vertical Sync (VSY , Pin 14.)
d. The internal detect will detect Vertical Sync to reset the vertical counter.
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 6.4 MHz.
c.
Input external Vertical Sync. (VIY , Pin 17) and Horizontal Sync. (Pin1) to synchronize the LCD module. External Horizontal Sync and External Vertical
