Interrupt Select (active high, input with internal pull-
down).
When 16/68# pin is HIGH 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. Interrupt out-
puts are enabled continuously when this pin is HIGH.
MCR bit-3 enables and disables 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 descrip-
tion for full detail. This pin must be LOW in the Motor-
ola bus interface mode. For the 64 pin packages, this
pin is bonded to VCC internally in the XR16M564D so
the INT outputs operate in the continuous interrupt
mode. This pin is bonded to GND internally in the
XR16M564 and therefore requires setting MCR bit-3
for enabling the interrupt output pins.

UART channels A-D Transmit Data and infrared trans-
mit data. Standard transmit and receive interface is
enabled when MCR[6] = 0. In this mode, the TX signal
will be a HIGH during reset, or idle (no data). Infrared
IrDA transmit and receive interface is enabled when
MCR[6] = 1. In the Infrared mode, the inactive state
(no data) for the Infrared encoder/decoder interface is
a logic 0.

prior to using auto RTS flow control, see EFR[6],
