Hi Video AE
Our customer Hik want to update their video reciever product, which integrate AD9388, to support 720P@30Hz DVI input.
When customer set below registers as "ADV7441A_AD9388A_Setting_Recommendations_RevM.pdf" 2.3.2 requirement
After writing these registers, customer read back to check. customer found that, 0x06[7:5] returns right value. 3'b010.
But, 0xB7[6] returns wrong value 1'b0. customer read back 0xB7,User Map, it return 0x00.
We din't find the description about 0xB7, User Map, cp_i2c_vsync_id_range in AD9388A_SW_RevC.pdf.
Questions are as below:
Can customer write 0xB7?
Could you share the description about 0xB7 in detal?
Do you have recommend setting list for 720P@30Hz HDMI/DVI input?
Thank you very much
Wayne
