I
Receive Data Input RX A-D. - These inputs are associated with
individual serial channel data to the ST16C454. The RX signal will
be a logic 1 during reset, idle (no data), or when the transmitter is
disabled. During the local loop-back mode, the RX input pin is
disabled and TX data is internally connected to the UART RX Input,
internally.

O
Transmit Data - These outputs are associated with individual serial
transmit channel data from the 454. The TX signal will be a logic
1 during reset, idle (no data), or when the transmitter is disabled.
During the local loop-back mode, the TX input pin is disabled and
TX data is internally connected to the UART RX Input.
