When 16/68# pin is at logic 1 for Intel bus interface, this ouput
becomes channel A interrupt output. The output state is defined by
the user and through the software setting of MCR[3]. INTA is set to
the active mode when MCR[3] is set to a logic 1. INTA is set to the
three state mode when MCR[3] is set to a logic 0 (default). See
MCR[3].
When 16/68# pin is at logic 0 for Motorola bus interface, this output
becomes device interrupt output (active low, open drain). An exter-
nal pull-up resistor is required for proper operation.

When 16/68# pin is at logic 1 for Intel bus interface, these ouputs
become the interrupt outputs for channels B, C, and D. The output
state is defined by the user through the software setting of MCR[3].
The interrupt outputs are set to the active mode when MCR[3] is set
to a logic 1 and are set to the three state mode when MCR[3] is set
to a logic 0 (default). See MCR[3].
When 16/68# pin is at logic 0 for Motorola bus interface, these out-
puts are unused and will stay at logic zero level. Leave these out-
puts unconnected.

I
Interrupt Select (active high, input with internal pull-down).
When 16/68# pin is at logic 1 for Intel bus interface, this pin can be
used in conjunction with MCR bit-3 to enable or disable the INT A-D
pins or override MCR bit-3 and enable the interrupt outputs. Inter-
rupt outputs are enabled continuously by making this pin a logic 1.
Making this pin a logic 0 allows MCR bit-3 to enable and disable the
interrupt output pins. In this mode, MCR bit-3 is set to a logic 1 to
enable the continuous output. See MCR bit-3 description for full
detail. This pin must be at logic 0 in the Motorola bus interface
mode. Due to pin limitations on 64 pin packages, this pin is not
available. To cover this limitation, two 64 pin LQFP packages ver-
sions are offered. This pin is bonded to VCC internally in the
ST16C654D so the INT outputs operate in the continuous interrupt
mode. This pin is bonded to GND internally in the ST16C654 and
therefore requires setting MCR bit-3 for enabling the interrupt output
pins.
