These 6 registers together give the 192-bit Channel Status Information to embed over the Audio PCM data available in the memory to send them as AES data out when AES encoder is included.
|32bit AES value: 32-bit AES Channel Status value.
The 6 registers give the value in order of LSB to MSB. The register 0x12C corresponds to the bits [31:0] of 192-bit channel status, while register 0x140 corresponds to the bits [191:160]. This value is programmed onto all the channels.
