Description
PA0~PA2
PA3/PFD
PA4/TMR I/O
PA5/INT
PA6~PA7
Pull-high
Wake-up
PA3 or PFD
Bidirectional 8-bit input/output port. Each individual pin on this port can be config-
ured as a wake-up input by a configuration option. Software instructions determine
if the pin is a CMOS output or Schmitt Trigger input. Configuration options deter-
mine which pins on the port have pull-high resistors. Pins PA3, PA4 and PA5 are
pin-shared with PFD, TMR and INT, respectively.
PB0/AN0
PB1/AN1
PB2/AN2
I/O
PB3/AN3
Pull-high
Bidirectional 4-bit input/output port. Software instructions determine if the pin is a
CMOS output or Schmitt Trigger input. Configuration options determine which pins
on the port have pull-high resistors. 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 options are disabled automatically.
PD0/PWM I/O
Pull-high
PD0 or PWM
Bidirectional 1-bit input/output port. Software instructions determine if the pin is a
CMOS output or Schmitt Trigger input.
A configuration option determines if this pin has a pull-high resistor. The PWM out-
put is pin-shared with pin PD0 selected via a configuration option.
OSC1
OSC2
I
O
Crystal
or RC
OSC1, OSC2 are connected to an external RC network or external crystal, deter-
mined by configuration option, for the internal system clock. If the RC system clock op-
tion is selected, pin OSC2 can be used to measure the system clock at 1/4 frequency.

Note:
1. Each pin on PA can be programmed through a configuration option to have a wake-up function.
2. Individual pins can be selected to have a pull-high resistor.
3. Pins PB2/AN2~PB3/AN3 exist but are not bonded out on the 16-pin package.
4. unbonded pins should be setup as outputs or as inputs with pull-high resistors to conserve power.
