11: S/PDIF source data assigned to AC-LINK slot10/11.
Reserved
SPDIF 1: enable 0: disable (SPDIFO is in high impedance)
DRA 1: enable 0: disable
VRA. 1: enable 0: disable
If VRA = 0, ALC202 ADC/DAC operate at fixed 48KHz sampling rate. Otherwise, it
operates with variable sampling rate defined in MX2C and MX32. VRA also control write
operation of MX2Cand MX32.

Validity Control
(control V bit in Sub-Frame)
0: the V bit (valid flag) in sub-frame depends on whether the S/PDIF data is
under-run or over-run.
1: the V bit in sub-frame is always send as 1 to indicate the invalid data is not
suitable for receiver.
Default: 2000H
