Frame Sync.
Delineates the serial data and may indicate the particular channel, left or right and may be
an input or output. The format is based on M0, M1 and M2 pins.
Serial Data.
Audio data serial input pin.
Serial Port Mode Select.
Selects the format of FSYNC and the sample edge of SCK with respect to SDATA.
Channel Status Bit 7/Channel Status Bit 3
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.
Professional/Consumer Select.
Selects between professional mode (PRO low) and consumer mode (PRO high). This pin
defines the functionality of the channel status parallel pins. PRO is ignored in Transparent
Mode.
Channel Status Bit 1/Frequency Control 0.
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.
Channel Status Bit 6/Channel Status Bit 2.
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
Validity.
Validity bit serial input port. This bit is defined as per 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.
Channel Status Serial Input/Subcode Frame Clock.
In professional and consumer modes this pin is the channel status serial input port. In CD
mode this pin inputs the CD subcode frame clock.
User Bit.
User bit serial input port.
Channel Status Bit 9/Channel Status Bit 15.
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.
Emphasis 1/Channel Status Bit 8.
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.
Emphasis 0/Channel Status Bit 9.
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 of byte 1). EM0/C9 are ignored in
Transparent Mode.
Channel Status Block Output/Subcode Bit Clock.
In professional and consumer modes, the channel status block output is high for the first 15
bytes of channel status. In CD mode, this pin outputs the subcode bit clock.
Master Reset.
When low, all internal counters are reset.
