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[3] to enable or disable the 3-state interrupts,
INTA to INTD, or override MCR[3] and force continuous
interrupts. Interrupt outputs are enabled continuously by
making this pin a logic 1. Making this pin a logic 0 allows
MCR[3] to control the 3-state interrupt output. In this mode,
MCR[3] is set to a logic 1 to enable the 3-state outputs. This
pin is disabled in the 68 mode. Due to pin limitations on the
64-pin packages, this pin is not available. To cover this
limitation, the SC16C654DBIB64 version operates in the
continuous interrupt enable mode by bonding this pin to V
CC
internally. The SC16C654BIB64 operates with MCR[3]
control by bonding this pin to GND.
Input/Output Read strobe (active LOW).
This function is
associated with the 16 mode only. A logic 0 transition on this
pin will load the contents of an internal register defined by
address bits A[0:2] onto the SC16C654B/654DB data bus
(D[0:7]) for access by external CPU. This pin is disabled in
the 68 mode.
Input/Output Write strobe (active LOW).
This function is
associated with the 16 mode only. A logic 0 transition on this
pin will transfer the contents of the data bus (D[0:7]) from the
external CPU to an internal register that is defined by
address bits A[0:2]. When the 68 mode is selected
(PLCC68), this pin functions as R/W (see definition under
R/W).
Interrupt Request or Interrupt ‘A’.
This function is
associated with the 68 mode only. In the 68 mode, interrupts
from UART channels A-D are wire-ORed internally to
function as a single IRQ interrupt. This pin transitions to a
logic 0 (if enabled by the interrupt enable register) whenever
a UART channel(s) requires service. Individual channel
interrupt status can be determined by addressing each
channel through its associated internal register, using CS
and A[3:4]. In the 68 mode, and external pull-up resistor
must be connected between this pin and V
CC
. The function
of this pin changes to INTA when operating in the 16 mode
(see definition under INTA).

Reset.
In the 16 mode, a logic 1 on this pin will reset the
internal registers and all the outputs. The UART transmitter
output and the receiver input will be disabled during reset
time. (See
Section 7.11 “SC16C654B/654DB external reset
conditions”
for initialization details.) When 16/68 is a logic 0
(68 mode), this pin functions similarly, but as an inverted
reset interface signal, RESET.
