Signals/Connections
1.8 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 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 Directions Register (PRR0). The signal can be
configured as ESSI signal SC00 through the Port Control Register (PCR0).
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 PRR0. The signal can be configured as an ESSI signal
SC01 through PCR0.
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 PRR0. The signal can be configured as an ESSI signal
SC02 through PCR0.
This input is 5 V tolerant.
