This bit is the error flag for the channel status CRCError check. This bit does not clear until the receiver error regi
is read.
This bit is set, if there is no AES3/SPDIF stream present at the AES3/SPDIF receiver. Once read, it remains high and
does not generate an interrupt unless it changes state.
This bit is set, if a biphase or parity error occurred in the AES3/SPDIF stream. This bit is not cleared until the register is
read.
This bit is set, if the PLL has locked or cleared when the PLL loses lock. Once read, it remains in its state and does not
