DSP56371 Data Sheet, Rev. 4.1
Serial Data Output 4_1—When programmed as a transmitter,
SDO4_1 is used to transmit data from the TX4 serial transmit shift
register.
Serial Data Input 1_1—When programmed as a receiver,
SDI1_1 is used to receive serial data into the RX1 serial receive
shift register.
Port E7—When the ESAI_1 is configured as GPIO, this signal is
individually programmable as input, output, or internally
disconnected.
The default state after reset is GPIO disconnected.
Internal Pull down resistor.
This input is 5 V tolerant.
Serial Data Output 3—When programmed as a transmitter,
SDO3_1 is used to transmit data from the TX3 serial transmit shift
register.
Serial Data Input 2—When programmed as a receiver, SDI2_1
is used to receive serial data into the RX2 serial receive shift
register.
Port E8—When the ESAI_1 is configured as GPIO, this signal is
individually programmable as input, output, or internally
disconnected.
The default state after reset is GPIO disconnected.
Internal Pull down resistor.
This input is 5 V tolerant.
Serial Data Output 2—When programmed as a transmitter,
