Dear Sir/Madam,


I got the following questions from our customer.


After I make change the setting of audio when I input the signal of 480i YCbCr444 8bit HDMI, then the channel status of input(register setting) become unstable.


So when the setting of PCM 96kHz more than 3ch, I/O Map address 0x5D bit8 become 1, and the value of Rx Main Map address 0x39(frequency setting) is changeable in always.

It does not become 0, even if the interrupt make clear.


And when PCM 96kHz 2ch, PCM 48kHz 3ch, except for 480i inout resolution,

then the value of frequency setting is fixed.

It become 0, after the interrupt make clear.


How should we try to adjust the registers or hard ware?

Do you have any comments for these?


Thanks Kaos
