I
Intel or Motorola Bus Select (input with internal pull-up).
When 16/68# pin is at logic 1, 16 or Intel Mode, the device will oper-
ate in the Intel bus type of interface.
When 16/68# pin is at logic 0, 68 or Motorola mode, the device will
operate in the Motorola bus type of interface.
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
This input provides the clock for UART channel C. An external 16X
baud clock or the crystal oscillator’s output, XTAL2, must be con-
nected to this pin for normal operation. This input may also be used
with MIDI (Musical Instrument Digital Interface) applications when
an external MIDI clock is provided. This pin is only available in the
100-pin QFP package.

No Connection. These pins are not used in either the Intel or Motor-
ola bus modes. These pins are open, but typically, should be con-
nected to GND for good design practice.
