O
Multi-purpose output. General purpose output or one of the
following functions can be selected for this output pin by
programming the Output Port Configuration Register bit 5:
-
RxBRDY
- Receive ready signal (Open drain output)
-RxBFULL
- Receive FIFO full signal (Open drain output)

I
Crystal input 1 or external clock input. A crystal can be
connected to this pin and XTAL2 pin to utilize the internal
oscillator circuit. An external clock can be used to clock
internal circuit and baud rate generator for custom transmis-
sion rates.

O
Crystal input 2 or buffered clock output. See XTAL1.
-RESET

I
Master reset. (active low) A low on this pin will reset all the
outputs and internal registers. The transmitter output and
the receiver input will be disabled during reset time.

O
Interrupt output (open drain active low) This pin goes low upon
occurrence of one or more of eight maskable interrupt condi-
tions (when enabled by the interrupt mask register) . CPU can
read the interrupt status register to determine the interrupting
condition(s). This output requires a pull-up resistor.
