Pin Description
Pin type: I=Input, O=Output, I/O= Input/output, OD=Output Open Drain.
Factory Test Mode
If the IOR#, IOW# and CS# pins are all asserted (at a logic 0), the 864 will enter a Factory Test Mode.

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 operation.
This input may also be used with MIDI (Musical Instrument Digital Interface) applications
when an external MIDI clock is provided.
When 16/68# pin is at logic 1 for Intel bus interface, this input becomes the Reset pin
(active high). In this case, a 40 ns minimum logic 1 pulse on this pin will reset the internal
registers and all outputs. The UART transmitter output will be held at logic 1, the receiver
input will be ignored and outputs are reset during reset period
pin is at a logic 0 for Motorola bus interface, this input becomes Reset# pin (active low).
This pin functions similarly, but instead of a logic 1 pulse, a 40 ns minimum logic 0 pulse
will reset the internal registers and outputs.
