Extraction of channel status bits into channel status registers is configurable. When enabled, channel status registers hold the 192-bit channel status information. User can select the channel pair from which channel status should be extracted.
After one complete audio block is received, an interrupt
asserted to indicate that data in channel status registers (0x48 to 0x5C) are valid.
Another interrupt is provided to indicate the change in channel status information from its previous value.
