DSP56367 Technical Data, Rev. 2.1
Serial Data Output 4—When programmed as a transmitter, SDO4 is used to
transmit data from the TX4 serial transmit shift register.
Serial Data Input 1—When programmed as a receiver, SDI1 is used to
receive serial data into the RX1 serial receive shift register.
Port C 7—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 3.3V tolerant.
Serial Data Output 3—When programmed as a transmitter, SDO3 is used to
transmit data from the TX3 serial transmit shift register.
When enabled for ESAI_1 operation, this is the ESAI_1 Serial Data Output 3.
Serial Data Input 2—When programmed as a receiver, SDI2 is used to
receive serial data into the RX2 serial receive shift register.
When enabled for ESAI_1 operation, this is the ESAI_1 Serial Data Input 2.
Port C 8—When the ESAI is configured as GPIO, this signal is individually
programmable as input, output, or internally disconnected.
When enabled for ESAI_1 GPIO, this is the Port E 8 signal.
The default state after reset is GPIO disconnected.
This input is 3.3V tolerant.
Serial Data Output 2—When programmed as a transmitter, SDO2 is used to
transmit data from the TX2 serial transmit shift register.
When enabled for ESAI_1 operation, this is the ESAI_1 Serial Data Output 2.
Serial Data Input 3—When programmed as a receiver, SDI3 is used to
receive serial data into the RX3 serial receive shift register.
When enabled for ESAI_1 operation, this is the ESAI_1 Serial Data Input 3.
Port C 9—When the ESAI is configured as GPIO, this signal is individually
programmable as input, output, or internally disconnected.
When enabled for ESAI_1 GPIO, this is the Port E 9 signal.
The default state after reset is GPIO disconnected.
This input is 3.3V tolerant.
Serial Data Output 1—SDO1 is used to transmit data from the TX1 serial
transmit shift register.
When enabled for ESAI_1 operation, this is the ESAI_1 Serial Data Output 1.
Port C 10—When the ESAI is configured as GPIO, this signal is individually
programmable as input, output, or internally disconnected.
When enabled for ESAI_1 GPIO, this is the Port E 10 signal.
The default state after reset is GPIO disconnected.
This input is 3.3V tolerant.
