SCKR
Input or output
GPIO
disconnected
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.
PC0
Input, output, or
disconnected
Port C0—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.
Internal Pull down resistor.
This input is 5 V tolerant.
SCKT
Input or output
GPIO
disconnected
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.
PC3
Input, output, or
disconnected
Port C3—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.
Internal Pull down resistor.
This input is 5 V tolerant.
SDO5
Output
GPIO
disconnected
Serial Data Output 5—When programmed as a transmitter, SDO5
is used to transmit data from the TX5 serial transmit shift register.
SDI0
Input
Serial Data Input 0—When programmed as a receiver, SDI0 is
used to receive serial data into the RX0 serial receive shift register.
PC6
Input, output, or
disconnected
Port C6—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.
Internal Pull down resistor.
This input is 5 V tolerant.
