Validity bit serial input port. This bit is defined according to the digital audio standards wherein
V = 0 signifies the audio signal is suitable for conversion to analog. V = 1 signifies the audio
signal is not suitable for conversion to analog, i.e. invalid. V is sampled once per subframe
User bit serial input port is sampled once per subframe.
Selects between professional mode (PRO low) and consumer mode (PRO high). This pin
defines the functionality of the next seven pins. PRO must be low for Transparent Mode, but
will have no effect on the channel status bits.
In professional mode, C9 is the inverse of channel status bit 9 (bit 1 of byte 1). In consumer
mode, C15 is the inverse of channel status bit 15 (bit 7 of byte 1). C9/C15 are ignored in
Transparent Mode.
In professional mode, EM0 and EM1 encode channel status bits 2, 3, and 4. In consumer mode,
C9 is the inverse of channel status bit 9 (bit 1 or byte 1). EMO/C9 are ignored in Transparent
Mode.
In professional mode, EM0 and EM1 encode channel status bits 2, 3, and 4. In consumer mode,
C8 is the inverse of channel status bit 8 (bit 0 of byte 1). EM1/C8 are ignored in Transparent
Mode.
In professional mode, C7 is the inverse of channel status bit 7. In consumer mode, C3 is the
inverse of channel status bit 3. C7/C3 are ignored in Transparent Mode.
In professional mode, C6 is the inverse of channel status bit 6. In consumer mode, C2 is the
inverse of channel status bit 2. C6/C2 are ignored in Transparent Mode.
In professional mode, C1 is the inverse of channel status bit 1. In consumer mode, FC0 and
FC1 are encoded versions of channel status bits 24 and 25 (bits 0 and 1 of byte 3). When FC0
and FC1 are both high, CD mode is selected. C1/FC0 are ignored in Transparent Mode.
