Clear to Send (Active-LOW).
These inputs are associated with individual UART
channels, A through B. A logic 0 on the CTS pin indicates the modem or data set is ready
to accept transmit data from the SC16C652. Status can be tested by reading MSR[4].
This pin has no effect on the UART’s transmit or receive operation.
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 SC16C652 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 DTR 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.
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.
Request to Send (Active-LOW).
These outputs are associated with individual UART
channels, A through B. A logic 0 on the RTS 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
SC16C652 receive input circuits, A-B. 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 connected to the UART RX input, internally.
Transmit data A, B.
These outputs are associated with individual serial transmit channel
data from the SC16C652. 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 output pin is
disabled and TX data is internally connected to the UART RX input.
