Description
Bidirectional 8-bit input/output port. Each individual bit on this port can be
configured as a wake-up input using the PAWU register. Software instruc-
BZ/BZ
tions determine if the pin is a CMOS output or Schmitt trigger input. A
I/O
pull-high resistor can be connected to each pin using the PAPU register.
PFD
Pins PA0, PA1 and PA3 are shared with BZ, BZ and PFD respectively, the
function of which is chosen via configuration option. Pins PA0~PA3 can
also be setup as open drain pins using the MISC register.

¾
connected to each pin using the PBPU register. PB is pin-shared with the
A/D input pins. The A/D inputs are selected via software instructions.
Once selected as an A/D input, the I/O function and pull-high resistor
selections are disabled automatically.

¾
connected to each pin using the PDPU register. The PWM outputs,
PWM0~PWM3, are pin shared with pins PD0~PD3, the function of which
is chosen using the PWM registers. Pins PD4~PD7 are pin-shared with
INT0, INT1, TMR0 and TMR1 respectively.
COM2~COM0 are the LCD common outputs. A bit in the LCD Control
O
¾
Register determines if pin COM3/SEG32 is configured as a segment
driver or as a common output driver.
