AD9889B, EDID Tries, 0xC9

Question asked by rleopold on Oct 3, 2013

Working on a design where I need to read and analyze the EDID information.  I wait for a HPD and RXSense then power up the part and monitor 0x96 bit 2 for EDID Ready.  I also monitor 0xC9 so that if it goes to zero I jump out of the loop.  I don't want to get stuck in an infinite loop if there happens to be no EDID.  The problem I have is I am never seeing anything other than the default value, 0x03, back from register 0xC9.  Has anyone successfully used the EDID Tries register in the AD9889B?  If there are any examples of C code etc. on how people set this part up for EDID extraction that would be very helpful.  Thank you.
