Remarks
Valid at only register “EX”=0 (at exter-
nal synchronous) (Note 2, 3 and 4)
Refer to Table 3, 4, 7 and 8.
Only at register “DSP1XX”
= 1 (XX = 00 to 16) is valid.
Method of sync separation from composite video.

Case 1 condition: vertical sync must repeat 2X
within 2 or 3; indicates this area.
Valid at only PAL and MPAL
mode.
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”.
