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.
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.
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.
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.
