I
Serial data input. The serial information (data) received from
serial port to XR68C92/192 receive input circuit. A mark
(high) is logic one and a space (low) is logic zero.This input
must be held at logic one when idle and during power down.
TXA, TXB

O
Serial data output. The serial data is transmitted via this pin
with additional start , stop and parity bits. This output will be
held in mark (high) state during reset, local loop back mode
or when the transmitter is disabled.

I
Multi-purpose input or Channel B receive external clock
input (received data is sampled on the rising edge of the
clock) or Timer/Counter External clock input. If not used, this
pin should be tied to VCC or GND.
