I
Carrier Detect (active LOW). These inputs are associated with individual UART
channels A through B. A logic 0 on this pin indicates that a carrier has been
detected by the modem for that channel.

I
Chip Select A, B (active LOW). This function is associated with individual
channels, A through B. These pins enable data transfers between the user CPU
and the SC16C652B for the channel(s) addressed. Individual UART sections (A, B)
are addressed by providing a logic 0 on the respective CSA, CSB pin.

I
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 SC16C652B. Status can be tested by
reading MSR[4]. This pin has no effect on the UART’s transmit or receive
operation.
CTSB

-
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.
DSRB

DTRA
34
-
O
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 SC16C652B 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.
DTRB

D0

27
I/O
Data bus (bi-directional). These pins are the 8-bit, 3-state data bus for
transferring information to or from the controlling CPU. D0 is the least signicant bit
and the rst data bit in a transmit or receive serial data stream.

21
O
Interrupt A, B (3-state). This function is associated with individual channel
interrupts, INTA, INTB. INTA, INTB are enabled when MCR bit 3 is set to a logic 1,
interrupts are enabled in the Interrupt Enable Register (IER), and is active when an
interrupt condition exists. Interrupt conditions include: receiver errors, available
receiver buffer data, transmit buffer empty, or when a modem status ag is
detected.
INTB

I
Read strobe (active LOW strobe). A logic 0 transition on this pin will load the
contents of an internal register dened by address bits A0 to A2 onto the
SC16C652B data bus (D0 to D7) for access by external CPU.
