ESSI Serial Control Pin 1 (SC01)
—The function of this pin is determined
by the selection of either synchronous or asynchronous mode. For
asynchronous mode, this pin is the receiver frame sync I/O. For
synchronous mode, this pin is used either for transmitter2 output or for
serial I/O flag 1.
Port C GPIO (4)
—This pin is a General Purpose I/O (GPIO) pin when the
ESSI is not in use.

ESSI Serial Control Pin 2 (SC02)
—This pin is used for frame sync I/O.
SC02 is 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 pin is the internally generated frame
sync signal. When configured as an input, this pin receives an external
frame sync signal for the transmitter (and the receiver in synchronous
operation).
Port C GPIO (5)
—This pin is a General Purpose I/O (GPIO) pin when the
ESSI is not in use.

ESSI Transmit Data (STD1)
—This output pin transmits serial data from
the ESSI Transmitter Shift Register.

ESSI Receive Data (SRD1)
—This input pin receives serial data and
transfers the data to the ESSI Receive Shift Register.
Port D GPIO (1)
—This pin is a General Purpose I/O (GPIO) pin when the
ESSI is not in use.

ESSI Serial Clock (SCK1)
—This bidirectional pin provides the serial bit
rate clock for the transmit section of the ESSI. The clock signal can be
continuous or gated and can be used by both the transmitter and receiver
in synchronous mode.
Port D GPIO (2)
—This pin is a General Purpose I/O (GPIO) pin when the
ESSI is not in use.

ESSI Serial Control Pin 0 (SC10)
—The function of this pin is determined
by the selection of either synchronous or asynchronous mode. For
asynchronous mode, this pin will be used for the receive clock I/O. For
synchronous mode, this pin is used either for transmitter1 output or for
serial I/O flag 0.
Port D GPIO (3)
—This pin is a General Purpose I/O (GPIO) pin when the
ESSI is not in use.
