Video Signal Input and Output
<Example>
(Addr:01H, D7)
VGCA4-0 bits
SAGC1-0 bits
PMVCM bit
VOUT pin
Clocks
When the only video function is used, the clocks are not needed to input.
(1) Power Up of VCOM : PMVCM bit = “0” → “1”
(2) Set up the output circuit(SAGC1-0bits) and GCA(VGCA4-0 bits)
(3 ) Power Up of Video-Amp : PMV bit = “0” → “1”
(4) Power Down of Video-Amp : PMV bit = “1” → “0”
PMV bit
The video signal that is input to VIN pin starts output from VOUT pin.
The output from VOUT pin stops. VOUT pin goes to AVSS.
If any audio functions are not used, VCOM can be powered-down(PMVCM bit =“0”)
