Note 1:
I – Debugging, Integrated on Chip; H – Debugging, Requires Debug Header.
2:
One pin is input-only.
3:
COM3 and SEG15 share the same physical pin, therefore SEG15 is not available when using 1/4 multiplex
displays.

Pin location selected by APFCON register setting. Default location.
Pin function can be moved using the APFCON register. Alternate location.
QFN package orientation is the same. No leads are present on the QFN package.
Note:
AV
DD
and AV
SS
are dedicated power connection pins for the on-board analog circuits of the PIC
®
microcontroller. The separate power pins help eliminate digital switching noise interference with the analog
circuitry inside the device, especially on larger devices with more I/O pins and larger switching currents on
the V
DD
/V
SS
pins. Customers typically connect these to the appropriate V
DD
or V
SS
connections on the
PCB, unless there is a lot of noise on the external power rails. In those situations, they will add additional
noise filtering components (like capacitors) on the AV
DD
/AV
SS
pins to help ensure good solid supply to the
analog modules inside the device.
