PCM DAC Rate (2Ch)
Default: BB80h
PCM LR ADC Rate (32h)
Default: BB80h
SPDIF Control (3Ah)
Default: 2A00h
Register 3Ah is a read/write register that controls SPDIF functionality and manages bit fields propa-
gated as channel status (or sub-frame in the V case). With exception of V, this register should only
be written to when the SPDIF transmitter is disabled (SPDIF bit register 2 Ah is 0). This ensures that
control and status information start up correctly at the beginning of SPDIF transmission. The default
is 2A00h which sets the SPDIF output sample rate at 48 KHz and the normal SPDIF expectations

Validity bit is set indicating each sub-frame’s samples are invalid. If
#V is 0, then it indicates that each sub-frame was transmitted and
received correctly by the interface.
