S-pin insertion detection
C-IN pins detect DC level to recognize if S-pin is inserted or not.
V Freq detection
The error range of X is −1 to +1.
Counts the vertical frequency of an input selected by SYNC SW.
To calculate the vertical frequency (Y) ;
Convert data read from V FREQ DET into decimal value and call it X.
When V-DET=0;
When V-DET=1;
Vertical frequency (Y) = 1 ÷ (X × 2.8607 × 10
