Composite Sync Spearation Function

Separation is performed during 1 in vertical blanking period

Separation is performed during 2 in vertical blanking period

Separation is performed during 3 in vertical blanking period

Setting disabled

(Note 1)

Valid at only register “EX”=0 (at exter-

nal synchronous) (Note 2, 3 and 4)

Notes 1: For internal synchronization, shut out (mute) the external video signal input, outside the IC. This avoids external video signal leaks

inside the IC.

2: For superimposed color displays, input an fsc signal which is synchronized with the color burst of the composite video signal (input to

the CVIN pin) to the OSCIN pin.

3: When EX (address 2B016) = “1” (internal synchronization), set the SCOR register to “0”.

4: When using a crystal oscillator (for the fsc input) between the OSCIN and OSCOUT pin, set the SCOR register to “0”.
