Serial Transmit Data 1 (TXD1)
—This signal transmits data from
the SCI 1 transmit data register.
Port E GPIO (3)
—This pin is a General Purpose I/O (GPIO) pin that
can individually be programmed as input or output pin.

ESSI Transmit Data (STD0)
—This output pin transmits serial data
from the ESSI Transmitter Shift Register.
Port C GPIO (0)
—This pin is a General Purpose I/O (GPIO) pin
when the ESSI is not in use.

ESSI Receive Data (SRD0)
—This input pin receives serial data
and transfers the data to the ESSI Receive Shift Register.
Port C GPIO (1)
—This pin is a General Purpose I/O (GPIO) pin
when the ESSI is not in use.

ESSI Serial Clock (SCK0)
—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 C GPIO (2)
—This pin is a General Purpose I/O (GPIO) pin
when the ESSI is not in use.

Input/Output
ESSI Serial Control Pin 0 (SC00)
—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 C GPIO (3)
—This pin is a General Purpose I/O (GPIO) pin
when the ESSI is not in use.

Input/Output
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.
