This buffer is a Schmitt Trigger input when configured as an external interrupt or LVP mode.
This buffer is a Schmitt Trigger input when used in Serial Programming mode.
This buffer is a Schmitt Trigger input when configured as general purpose I/O and a TTL input when used in the Parallel
Slave Port mode (for interfacing to a microprocessor bus).
This buffer is a Schmitt Trigger input when configured in RC Oscillator mode and a CMOS input otherwise.

PORTD is a bi-directional I/O port or parallel slave port when
interfacing to a microprocessor bus.
PORTE is a bi-directional I/O port.
Ground reference for logic and I/O pins.
Positive supply for logic and I/O pins.
These pins are not internally connected. These pins should be
left unconnected.
RE0 can also be read control for the parallel slave port, or
analog input 5.
RE1 can also be write control for the parallel slave port, or
analog input 6.
RE2 can also be select control for the parallel slave port,
or analog input 7.
