ADV7842 TMDS Clock Activity Detection

Question asked by JeffMcD on Feb 29, 2012

In the Hardware User Guide (UG214), in section 8.16, it lists three "Important" criteria needed for the TMDS clock detection function read at Addr 40, register 0x6a, bit 1, to work. I have found that there is one more setting that is needed. HDMI Register 0x9D must be set to 0x02 for this function to work. This register is not documented so I have no idea what it does.

 

Please add this to the document in the next update.

 

Thanks,

 

Jeff
