ADV7511W I2C Read Issues

Question asked by cfritz68 on Dec 17, 2015

I am having difficulty with the I2C read on the ADV7511W.  I am able to write to registers, but every read of a single register returns a 0x13?  I know my writes are working as I can change the HDMI output (register 0x41) but reading back I always get a hex 13? I have attached the read waveform. Any help would be appreciated.

 

Thanks,

Chris
