Output(Z)
Input/Output
Serial Transmit Data 0 (TXD0)
—This signal transmits data from the SCI
0 transmit data register.
Port E GPIO (1)
—This pin is a General Purpose I/O (GPIO) pin that can
individually be programmed as input or output pin.

Input/Output
Serial Receive Data 1 (RXD1)
—This input receives byte-oriented serial
data and transfers it to the SCI 1 receive shift register.
Port E GPIO (2)
—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.
95
SC00
GPIOC3
Input
/Output
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.
