C, D) are addressed by providing a low on the respective CSA through CSD pin.

Clear to send (active low). These inputs are associated with individual UART channels A

and B. A low on the CTS pins indicates the modem or data set is ready to accept

transmit data from the TL16C752C. Status can be checked by reading MSR[4]. These

pins only affect the transmit and receive operations when auto CTS function is enabled

through the enhanced feature register (EFR[7]), for hardware flow control operation.

Data bus (bidirectional). These pins are the eight-bit, 3-state data bus for transferring

ready for data exchange with the UART.

Data terminal ready (active low). These outputs are associated with individual UART

channels A through B. A low on these pins indicates that the TL16C752C is powered on

and ready. These pins can be controlled through the modem control register. Writing a 1

to MCR[0] sets the DTR output to low, enabling the modem. The output of these pins is

high after writing a 0 to MCR[0], or after a reset. These pins can also be used in the

RS-485 mode to control an external RS-485 driver or transceiver.
