I
UART channels A-D Carrier-Detect (active low) or
general purpose input. This input should be connected
to VCC when not used. This input has no effect on the
UART.

I
Intel or Motorola Bus Select (input with internal pull-
up).
When 16/68# pin is HIGH, 16 or Intel Mode, the device
will operate in the Intel bus type of interface.
When 16/68# pin is LOW, 68 or Motorola mode, the
device will operate in the Motorola bus type of inter-
face.
Motorola bus interface is not available on the 64 pin
package.

I
Baud-Rate-Generator Input Clock Prescaler Select for
channels A-D. This input is only sampled during power
up or a reset. Connect to VCC for divide by 1 (default)
and GND for divide by 4. MCR[7] can override the
state of this pin following a reset or initialization. See
MCR bit-7 and
Figure 6 in the Baud Rate Generator
section.

I
When 16/68# pin is HIGH for Intel bus interface, this
input becomes the Reset pin (active high). In this
case, a 40 ns minimum HIGH pulse on this pin will
reset the internal registers and all outputs. The UART
transmitter output will be held HIGH, the receiver input
will be ignored and outputs are reset during reset
period (Table 17). When 16/68# pin is at LOW for
Motorola bus interface, this input becomes Reset# pin
(active low). This pin functions similarly, but instead of
a HIGH pulse, a 40 ns minimum LOW pulse will reset
the internal registers and outputs.
Motorola bus interface is not available on the 64 pin
package.
