O
Data transfer acknowledge (three-state active low output).
During Read, Write, or interrupt cycle goes low to indicate
proper transfer of data between the CPU and XR68C92/
192.
RX A/B

29,5
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.
TX A/B
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. The TX will be held
in mark (high) state during reset, local loop back mode or
when the transmitter is disabled.
