Register 0x3A is a read/write register that controls SPDIF functionality and manages bit fields propagated as channel status (or subframe in the V case). With the
exception of V, this register should be written to only when the SPDIF transmitter is disabled (SPDIF bit in Register 0x2A is 0). This ensures that control and status
information start up correctly at the beginning of SPDIF transmission.

1 = Professional use of channel status.
0 = Consumer.

1 = Data is non-PCM format.
0 = Data is PCM format.

1 = Copyright is asserted.
0 = Copyright is not asserted.

Pre-emphasis
1 = Filter pre-emphasis is 50 µs/15 µs.
0 = Pre-emphasis is none.

Programmed according to IEC standards, or as appropriate.
SPSR [1:0]
SPDIF Transmit
Sample Rate
SPSR [1:0] = 00: Transmit sample rate is 44.1 kHz.
SPSR [1:0] = 01: Reserved.
SPSR [1:0] = 10: Transmit sample rate is 48 kHz (reset default).
SPSR [1:0] = 11: Not supported.
V
Validity
This bit affects the validity flag (Bit 28 transmitted in each SPDIF L/R subframe) and enables the SPDIF
transmitter to maintain connection during error or mute conditions.
V = 1: Each SPDIF subframe (L + R) has Bit 28 set to 1. This tags both samples as invalid.
V = 0: Each SPDIF subframe (L + R) has Bit 28 set to 0 for valid data and 1 for invalid data (error
condition).
When V = 0, asserting the VFORCE bit (D15) in Register 0x2A (Ext’d Audio Stat/Ctrl) forces the validity
flag low, marking both samples as valid.

Register 0x60 is a read/write register that controls the equalizer functionality and data setup. This register contains the biquad and coefficient address pointer, which
is used in conjunction with the EQ data register (0x78) to set up the equalizer coefficients. The reset default disables the equalizer function until the coefficients can be
properly set up by the software and sets the symmetry bit to allow equal coefficients for left and right channels.
All registers are not shown, and bits containing an X are assumed to be reserved.
