I
Serial data input. The serial information (data) received from
serial port to XR88C92/192 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
33,13
30,11
28,6
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.
RESET

I
Master Reset (active high). A high on this pin will reset all the
outputs and internal registers. The transmitter output and
the receiver input will be disabled during reset time.
