I
Chip Select A, B, C, D (active low) - This function is
associated with the 16 mode only, and for individual chan-
nels, A through D. When in 16 Mode, these pins enable
data transfers between the user CPU and the ST16C554D
for the channel(s) addressed. Individual UART sections (A,
B, C, D) are addressed by providing a logic 0 on the
respective -CS A-D pin. When the 68 mode is selected, the
functions of these pins are reassigned. 68 mode functions
are described under the their respective name/pin head-
ings.

I/O
Data Bus (Bi-directional) - These pins are the eight bit, three
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.

O
Interrupt A, B, C, D (active high) - This function is associated
with the 16 mode only. These pins provide individual
channel interrupts, INT A-D. INT A-D are enabled when
MCR bit-3 is set to a logic 1, interrupts are enabled in the
interrupt enable register (IER), and when an interrupt con-
dition 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 reassigned. 68
mode functions are described under the their respective
name/pin headings.

I
Interrupt Select. (active high, with internal pull-down) - This
function is associated with the 16 mode only. When the 16
mode is selected, this pin can be used in conjunction with
MCR bit-3 to enable or disable the three state interrupts, INT
A-D or override MCR bit-3 and force continuous interrupts.
Interrupt outputs are enabled continuously by making this
