NAME
FUNCTION
General-Purpose, Digital, I/O, Type-D Port; LCD Segment-Driver Output; External
Edge-Selectable Interrupt. This port functions as both bidirectional I/O pins and LCD
segment-drive outputs. All port pins are defaulted as inputs with weak pullups after a
reset. The port pads can be configured as an external interrupt for pins 7 to 4. If the
external interrupt is enabled, the LCD function on the associated pin is disabled.
Setting the PCF3 bit enables the LCD for all pins on this port and disables the general-
purpose I/O function on all pins.
It is possible to mix the LCD and interrupt functions on the same port. To do this, the
interrupt enable must be established prior to setting the PCF0 bit. Care must be taken
not to enable the external interrupt while the LCD is in normal operational mode, as
this could result in potentially harmful contention between the LCD controller output
and the external source connected to the interrupt input.

LCD Segment-Driver Output; LCD Common-Drive Output. The selection of a pin
function as either segment or its alternative common-mode signal is controlled by the
choice of duty cycle (DUTY1:0).
