I would like to know channels A/B/C gain value after enable AGC function as below.
When I enable AGC function of ADV7604, is it possible to read back A/B/C channels register value after auto gain adjustment?
a. This configuration is enabled by setting AGC_MODE_MAN to 1 and GAIN_MAN to 0 for VGA and YPbPr input mode.
b. Read back registers, CP Map, Reg 0x73~0x74 for A/B/C gain
but I found there are no any changed. Is any step I missing?
