PE0
Input, output, or
disconnected
GPIO
disconnected
Port E 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 cannot tolerate 5 V.
SCKT_1
Input or output
GPIO
disconnected
Transmitter Serial Clock_1
—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.
PE3
Input, output, or
disconnected
GPIO
disconnected
Port E 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 cannot tolerate 5 V.
SDO5_1
Output
GPIO
disconnected
Serial Data Output 5_1
—When programmed as a transmitter, SDO5 is
used to transmit data from the TX5 serial transmit shift register.
SDI0_1
Input
GPIO
disconnected
Serial Data Input 0_1
—When programmed as a receiver, SDI0 is used to
receive serial data into the RX0 serial receive shift register.
PE6
Input, output, or
disconnected
GPIO
disconnected
Port E 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 cannot tolerate 5 V.
SDO4_1
Output
GPIO
disconnected
Serial Data Output 4_1
—When programmed as a transmitter, SDO4 is
used to transmit data from the TX4 serial transmit shift register.
SDI1_1
Input
GPIO
disconnected
Serial Data Input 1_1
—When programmed as a receiver, SDI1 is used to
receive serial data into the RX1 serial receive shift register.
PE7
Input, output, or
disconnected
GPIO
disconnected
Port E 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 5 V tolerant.
