ESSI Transmit Data (STD1)—This output pin transmits serial data
from the ESSI Transmitter Shift Register.
Port D GPIO (0)—This pin is a General Purpose I/O (GPIO) pin when
the ESSI is not in use.

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.

ESSI Serial Control Pin 1 (SC11)—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 D GPIO (4)—This pin is a General Purpose I/O (GPIO) pin when
the ESSI is not in use.

ESSI Serial Control Pin 2 (SC12)—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 D GPIO (5)—This pin is a General Purpose I/O (GPIO) pin when
the ESSI is not in use.
