DSP56364 Technical Data, Rev. 4.1
Port C 4—When the ESAI is configured as GPIO, this signal is individually
programmable as input, output, or internally disconnected.
The default state after reset is GPIO disconnected.
This input is 5 V tolerant.
Receiver Serial Clock—SCKR provides the receiver serial bit clock for the
ESAI. The SCKR operates as a clock input or output used by all the enabled
receivers in the asynchronous mode (SYN=0), or as serial flag 0 pin in the
synchronous mode (SYN=1).
When this pin is configured as serial flag pin, its direction is determined by the
RCKD bit in the RCCR register. When configured as the output flag OF0, this
pin will reflect the value of the OF0 bit in the SAICR register, and the data in the
OF0 bit will show up at the pin synchronized to the frame sync in normal mode
or the slot in network mode. When configured as the input flag IF0, the data
value at the pin will be stored in the IF0 bit in the SAISR register, synchronized
by the frame sync in normal mode or the slot in network mode.
Port C 0—When the ESAI is configured as GPIO, this signal is individually
programmable as input, output, or internally disconnected.
The default state after reset is GPIO disconnected.
This input is 5 V tolerant.
Transmitter Serial Clock—This signal provides the serial bit rate clock for the
ESAI. SCKT is a clock input or output used by all enabled transmitters and
receivers in synchronous mode, or by all enabled transmitters in asynchronous
mode.
Port C 3—When the ESAI is configured as GPIO, this signal is individually
programmable as input, output, or internally disconnected.
The default state after reset is GPIO disconnected.
This input is 5 V tolerant.
Serial Data Output 5—When programmed as a transmitter, SDO5 is used to
transmit data from the TX5 serial transmit shift register.
Serial Data Input 0—When programmed as a receiver, SDI0 is used to receive
serial data into the RX0 serial receive shift register.
Port C 6—When the ESAI is configured as GPIO, this signal is individually
programmable as input, output, or internally disconnected.
The default state after reset is GPIO disconnected.
This input is 5 V tolerant.
Serial Data Output 4—When programmed as a transmitter, SDO4 is used to
transmit data from the TX4 serial transmit shift register.
