DS90UB947-Q1: How to prevent the AV Mute

Part Number: DS90UB947-Q1

Hi team,

Could you help to have a look as below questions:

1. When using UB947-UB948, under what circumstances will 948 enter AV mute?

2. How to prevent AV mute? Do you need to set 947 0x04 [4] = 1 and 948 0x03 [1] = 1 at the same time?

3. Is it recommended to increase this register directly in the 947/948 initialization code?

Thank you.

Best regards,

Ansel
