I
Data Set Ready (active LOW). These inputs are associated
with individual UART channels, A through B. A logic 0 on this
pin indicates the modem or data set is powered-on and is ready
for data exchange with the UART. This pin has no effect on the
UART’s transmit or receive operation.

Data Terminal Ready (active LOW). These outputs are
associated with individual UART channels, A through B.
A logic 0 on this pin indicates that the SC16C2550B is
powered-on and ready. This pin can be controlled via the
Modem Control Register. Writing a logic 1 to MCR[0] will set
the DTRn output to logic 0, enabling the modem. This pin will
be a logic 1 after writing a logic 0 to MCR[0] or after a reset.
This pin has no effect on the UART’s transmit or receive
operation.

I
Ring Indicator (active LOW). These inputs are associated
with individual UART channels, A through B. A logic 0 on this
pin indicates the modem has received a ringing signal from the
telephone line. A logic 1 transition on this input pin will generate
an interrupt.

O
Request to Send (active LOW). These outputs are associated
with individual UART channels, A through B. A logic 0 on the
RTSn pin indicates the transmitter has data ready and waiting
to send. Writing a logic 1 in the Modem Control Register
MCR[1] will set this pin to a logic 0, indicating data is available.
After a reset this pin will be set to a logic 1. This pin has no
effect on the UART’s transmit or receive operation.

Receive data A, B. These inputs are associated with individual
serial channel data to the SC16C2550B receive input circuits,
A and B. The RXn signal will be a logic 1 during reset, idle (no
data) or when the transmitter is disabled. During the local
Loopback mode, the RXn input pin is disabled and TX data is
connected to the UART RX input, internally.
