type
ated with the 68 mode only. In the 68 mode, interrupts from
UART channels A-D are WIRE-OR’ed” internally to function
as a single IRQ interrupt. This pin transitions to a logic 0 (if
enabled by the interrupt enable register) whenever a UART
channel(s) requires service. Individual channel interrupt
status can be determined by addressing each channel
through its associated internal register, using -CS and A3-
A4. In the 68 mode an external pull-up resistor must be
connected between this pin and Vcc. The function of this pin
changes to INTA when operating in the 16 mode, see
definition under INTA.

O
Infrared Transmit Data Output (IrDA) - This function is
associated with 100 pin packages only. These pins provide
separate infrared IrDA TX outputs for UART channel’s (A-
D). The serial infrared IRTX data is transmitted via these
pins with added start, stop and parity bits. The IRTX signal
will be a logic 0 during reset, idle (no data), or when the
transmitter is disabled. MCR bit-6 selects the standard
modem or infrared interface.

I
MIDI (Musical Instrument Digital Interface) Clock Input -
This function is associated with 100 pin packages only. RXC
and TXC can function as MIDI input/output ports when an
external MIDI Clock is provided at this pin. External Clock
or a crystal is connected to the XTAL1/2 pins for normal
operation (see XTAL 1 & 2).

Reset. - In the 16 mode a logic 1 on this pin will reset the
internal registers and all the outputs. The UART transmitter
output and the receiver input will be disabled during reset
time. (See ST16C654 External Reset Conditions for initial-
ization details.) When 16/-68 is a logic 0 (68 mode), this pin
functions similarly but, as an inverted reset interface signal,
-RESET.
