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 Motor-
ola bus type of interface.
Motorola bus interface is not available on
the 64 pin package.

I
Baud-Rate-Generator Input Clock Pres-
caler 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 over-
ride the state of this pin following a reset or
initialization. See MCR bit-7 and
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 connected to this pin for normal opera-
tion. This input may also be used with MIDI
(Musical Instrument Digital Interface) appli-
cations when an external MIDI clock is pro-
vided. This pin is only available in the 100-
pin QFP package.
