CMOS level output that outputs a biphase-mark encoded (S/PDIF) IEC60958 signal or digital
audio data which is capable of carrying two channels of PCM digital audio. OUTPUT
AUDATA4, GPIO28 — Digital Audio Output 4, General Purpose I/O
PCM digital-audio data output. This pin can act as a general-purpose input or output that can
be individually configured and controlled by DSPC. BIDIRECTIONAL - Default: OUTPUT
AUDATA5, GPIO29 — Digital Audio Output 5, General Purpose I/O
PCM digital-audio data output. This pin can act as a general-purpose input or output that can
be individually configured and controlled by DSPC. BIDIRECTIONAL - Default: OUTPUT
AUDATA6, GPIO30 — Digital Audio Output 6, General Purpose I/O
PCM digital-audio data output. This pin can act as a general-purpose input or output that can
be individually configured and controlled by DSPC. BIDIRECTIONAL - Default: OUTPUT
AUDATA7, XMT958B, GPIO31 — Digital Audio Output 7, S/PDIF Transmitter, General Purpose I/O
CMOS level output that contains a biphase-mark encoded (S/PDIF) IEC60958 signal or digital
audio data which is capable of carrying two channels of PCM digital audio. This pin can also
act as a general-purpose input or output that can be individually configured and controlled by
DSPC. BIDIRECTIONAL - Default: OUTPUT
DBCK — Debug Clock
Must be tied high to 3.3k ohm resistor. INPUT
DBDA — Debug Data
Must be tied high to 3.3k ohm resistor. BIDIRECTIONAL - Default: INPUT
SLCKN, GPIO22 — PCM Audio Input Bit Clock, General Purpose I/O
Digital-audio bit clock that is an input. SCLKN operates asynchronously from all other DSPAB
clocks. The active edge of SCLKN can be programmed by the DSP. This pin can act as a
general-purpose input or output that can be individually configured and controlled by DSPC.
BIDIRECTIONAL - Default: INPUT
LRCLKN, GPIO23 — PCM Audio Input Sample Rate Clock, General Purpose I/O
Digital-audio frame clock input. LRCLKN operates asynchronously from all other DSPAB
clocks. The polarity of LRCLKN for a particular subframe can be programmed by the DSP.
This pin can act as a general-purpose input or output that can be individually configured and
controlled by DSPC. BIDIRECTIONAL - Default: INPUT
SDATAN0, GPIO24 — PCM Audio Input Data, General Purpose I/O
Digital-audio PCM data input. This pin can act as a general-purpose input or output that can
be individually configured and controlled by DSPC. BIDIRECTIONAL - Default: INPUT
SDATAN1, GPIO25 — PCM Audio Input Data, General Purpose I/O
AVR340 harman/kardon
