Freeze gain of ADV7482

gattu on Oct 12, 2021

Hi,

I would like to know the setting (Freeze gain) of LAGC [2:0] = b'111.
After automatically adjusting the gain with AGC [2: 0] = b'010 etc., is it possible to fix the gain value in that state by setting LAGC [2:0] = b'111 (Freeze gain)?

Regards,
Gattu
