during power up the PD/AD pin of ADV7511 is pulled up with 10k and I can switch this pin with an FPGA. The device responds to address 0x7a and reg 0x42 reports active low for power down polarity. I switch the external PD to high level. If I write 0x10 to reg 0x41 I will read back 0x50. So I can't power up the device. Is there anonther register to power up the device?
Thank you for your help.
