Hello All,

 

Please let me know about algorithm for HDMI mode detection of HDMI_MODE, Addr 68 (HDMI), Address 0x05[7] (Read Only)
which is described in ADV7612 Hardware User Guide (UG-216) P.41

 

Reason which need above information is as following.

When we use HDMI_MODE(address=0x68,0x05 bit7), read value is “0” rarely.
Then we input HDMI signal to ADV7612 and interruption for HDMI_ mode change is not generated .

 

Regards,
