Enhanced Serial Audio Interface
MOTOROLA
DSP56367
2-17
SDO4
Output
GPIO disconnected
Serial Data Output 4—When programmed as a transmitter, SDO4 is used to
transmit data from the TX4 serial transmit shift register.
SDI1
Input
Serial Data Input 1—When programmed as a receiver, SDI1 is used to
receive serial data into the RX1 serial receive shift register.
PC7
Input, output, or
disconnected
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.
SDO3/SD
O3_1
Output
GPIO disconnected
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.
SDI2/SDI
2_1
Input
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.
PC8/PE8
Input, output, or
disconnected
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.
SDO2/SD
O2_1
Output
GPIO disconnected
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.
SDI3/SDI
3_1
Input
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.
PC9/PE9
Input, output, or
disconnected
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.
SDO1/SD
O1_1
Output
GPIO disconnected
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.
PC10/PE1
0
Input, output, or
disconnected
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.
