Signals/Connections
2.8 Enhanced Synchronous Serial Interface 0 (ESSI0)
Two synchronous serial interfaces (ESSI0 and ESSI1) provide a full-duplex serial port for serial
communication with a variety of serial devices, including one or more industry-standard
CODECs, other DSPs, microprocessors, and peripherals that implement the Freescale serial
peripheral interface (SPI).

Serial Control 0
Functions in either Synchronous or Asynchronous mode. For Asynchronous
mode, this signal is the receive clock I/O (Schmitt-trigger input). For
Synchronous mode, this signal is either for Transmitter 1 output or Serial I/O
Flag 0.
Port C 0
The default configuration following reset is GPIO. For PC0, signal direction is
controlled through the Port C Direction Register (PRRC).
This signal is configured as SC00 or PC0 through the Port C Control Register
(PCRC). This input is 5 V tolerant.
Serial Control 1
Functions in either Synchronous or Asynchronous mode. For Asynchronous
mode, this signal is the receiver frame sync I/O. For Synchronous mode, this
signal is either Transmitter 2 output or Serial I/O Flag 1.
Port C 1
The default configuration following reset is GPIO. For PC1, signal direction is
controlled through PRRC.
This signal is configured as SC01 or PC1 through PCRC. This input is 5 V
tolerant.
Serial Control Signal 2
The frame sync for both the transmitter and receiver in Synchronous mode,
and for the transmitter only in Asynchronous mode. When configured as an
output, this signal is the internally generated frame sync signal. When
configured as an input, this signal receives an external frame sync signal for
the transmitter (and the receiver in synchronous operation).
Port C 2
The default configuration following reset is GPIO. For PC2, signal direction is
controlled through PRRC. This signal is configured as SC02 or PC2 through
PCRC. This input is 5 V tolerant.
