In ADV7511, there are the following registers.
Address : 0x0C bit7
Register: Audio Sampling Frequency Select"
Select source of audio sampling frequency for pixel repeat and I2S mode 4
0 = use sampling frequency from I2S stream
1 = use sampling frequency from I2C register
Address : 0x0C bit6
Register: Channel Status Override
Source of channel status bits when using I2S mode 4
0 = use channel status bits from I2S stream
1 = use channel status bits from I2C registers
Each register is used when "I2S mode 4"
I want to know about "I2S mode 4".
Please answer the following questions.
Q1. "I2S mode 4" is "AES3 direct mode" ?
Q2. "I2S mode 4" is equal to the mode of "I2S Format" register ?
Address : 0x0C bit1,0
Register: I2S Format
00 = Standard I2S mode
01 = right justified mode
10 = left justified mode
11 = AES3 direct mode
Q3. What is "I2S mode 4" ?
