Channel Status Select
0: Channel 1
1: Channel 2
Selects which channel status is used to derive AUDION, PEM, FS1 and FS0.
The de-emphasis filter, however, is always controlled by channel 1 in the Parallel Mode.
Status change flag mask bit
This bit is low to mask status change from being reported by ERF.
Parity mask bit
This bit is low to mask Parity Error, Biphase Error and Frame Length Error from being reported by
