Our customer want to detect inputted SD component video signal with HDMI Audio mode simultaneously.
Therefore, they set ADC_HDMI_SIMULT_MODE=1 and PRIM_MODE[3:0]=0100 (CVBS & HDMI AUDIO Mode)
To determine which video format inputted, they are polling the SDP_VIDEO_DETECTED_RAW bit.
However, the SDP_VIDEO_DETECTED_RAW bit is unstable when the ADV7842 could not detect inputted SD component.
In case of CVBS or YC (S-Video), the SDP_VIDEO_DETECTED_RAW bit is stable, no problem.
Should they need to read another registers?
Please advise to solve this issue as soon as possible.
