Clear to Send (active LOW). These inputs are
associated with individual UART channels A to D. A
logic 0 on the CTSn pin indicates the modem or data
set is ready to accept transmit data from the
SC16C554B/554DB. Status can be tested by reading
MSR[4]. This pin only affects the transmit or receive
operations when auto-CTS function is enabled via
MCR[5] for hardware flow control operation.

Data bus (bidirectional). These pins are the 8-bit,
3-state data bus for transferring information to or from
the controlling CPU. D0 is the least significant bit and
the first data bit in a transmit or receive serial data
stream.

Data Set Ready (active LOW). These inputs are
associated with individual UART channels, A through
D. 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 D. A logic 0 on this pin indicates that the
SC16C554B/554DB 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.

Interrupt A, B, C, D (active HIGH). This function is
associated with the 16 mode only. These pins provide
individual channel interrupts INTA to INTD.
INTA to INTD are enabled when MCR[3] is set to a
logic 1, interrupts are enabled in the Interrupt Enable
Register (IER), and when an interrupt condition exists.
Interrupt conditions include: receiver errors, available
receiver buffer data, transmit buffer empty, or when a
modem status flag is detected. When the 68 mode is
selected, the functions of these pins are re-assigned.
68 mode functions are described under their respective
name/pin headings.
