When 16/68# pin is HIGH for Intel bus interface, this out-
put becomes channel A interrupt output. The output state
is defined by the user through the software setting of
MCR[3]. INTA is set to the active mode and OP2A# out-
put LOW when MCR[3] is set to a logic 1. INTA is set to
the three state mode and OP2A# to HIGH when MCR[3]
is set to a logic 0. See MCR[3].
When 16/68# pin is LOW for Motorola bus interface, this
output becomes device interrupt output (active low, open
drain). An external pull-up resistor is required for proper
operation.

When 16/68# pin is HIGH for Intel bus interface, this out-
put becomes channel B interrupt output. The output state
is defined by the user through the software setting of
MCR[3]. INTB is set to the active mode and OP2A# out-
put to LOW when MCR[3] is set to a logic 1. INTA is set to
the three state mode and OP2A# to HIGH when MCR[3]
is set to a logic 0. See MCR[3].
When 16/68# pin is LOW for Motorola bus interface, this
output is not used.

UART channel A Transmitter Ready (active low). The
output provides the TX FIFO/THR status for transmit
channel A. See
Table 3. If it is not used, leave it uncon-
nected.

O
UART channel A Receiver Ready (active low). This out-
put provides the RX FIFO/RHR status for receive channel
A. See
Table 3. If it is not used, leave it unconnected.

UART channel B Transmitter Ready (active low). The
output provides the TX FIFO/THR status for transmit
channel B. See
Table 4. If it is not used, leave it uncon-

O
UART channel A Transmit Data or infrared encoder data.
Standard transmit and receive interface is enabled when
MCR[6] = 0. In this mode, the TX signal will be HIGH dur-
ing 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 LOW. If it is not used, leave
it unconnected.
