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
SDATAN2, GPIO26 — 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
SDATAN3, GPIO27 — 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
SCS
— Host Serial SPI Chip Select
SPI mode active-low chip-select input signal. INPUT
SCCLK — Serial Control Port Clock
This pin serves as the serial SPI clock input. INPUT
SCDIN — SPI Serial Control Data Input
In SPI mode this pin serves as the data input pin. INPUT
SCDOUT, SCDIO — Serial Control Port Data Input and Output
In SPI mode this pin serves as the data output pin. BIDIRECTIONAL - Default: OUTPUT in
SPI mode
INTREQ
— Control Port Interrupt Request
Open-drain interrupt-request output. This pin is driven low to indicate that DSPC has outgoing
control data and should be serviced by the host.
OPEN DRAIN I/O - Requires 3.3K Ohm Pull-Up
AVR340 harman/kardon
