Function
The serial data output for the Debug Port. Can also be used as a GPIO.
3.3V core supply.
Core ground.
Debug Port Bit Clock/Chip Status 1. The serial clock for the Debug Port
is provided when an input. When an output, provides information about
the chip status. Can also be used as GPIO
Debug Port Serial Input/Chip Status 0. The serial data input for the
Debug Port is provided when an input. When an output, provides
information about the chip status. Can also be used as GPIO.
Output Clock.
PLL Clock Ground Input. Ground connection for oscillator circuit.
PLL Clock Power Supply. Positive supply for PLL Clock Oscillator.
Crystal Oscillator Output. Crystal Oscillator output drive.
Crystal Oscillator Input. External Clock Input or crystal connection.
System Reset. A logic low level applied to RESET input initializes DSPs.
During Debug Mode if this pin is pulled low in while the DBRQN line is
pulled low then the DSP pointed to by the DBSEL pin will be reset.
3.3V Supply.
Ground.
SDI0 is a stereo digital audio data input pin channel 0.
SDI1 is a stereo digital audio data input pin channel 1.
SDI2 is a stereo digital audio data input pin channel 2.
SAI receive bit clock. Master or slave.
Left-Right clock for SAI Receiver. Master or slave.
3.3V Supply.
Ground.
SDO0 is a stereo digital audio data output pin channel 0.
SDO1 is a stereo digital audio data output pin channel 1.
SDO2 is a stereo digital audio data pin channel 2.
3.3V Supply.
Ground.
SAI transmit left/right clock. Master or slave.
SAI transmit bit clock. Master or slave.
Clock line for I²C bus. Schmitt trigger input.
Data line for I²C bus. Schmitt trigger input.
Bit clock for SPI control interface.
Slave select input pin for SPI control interface.
Serial Data Output for SPI type serial port when in SPI Master Mode and
Serial Data Input when in SPI Slave Mode.
Serial Data Input for SPI style serial port when in SPI Master Mode and
Serial Data Output when in SPI Slave Mode.
3.3V Supply.
