2: CCP2 and the USART are not available on the PIC16C64/64A/R64.
3: This buffer is a Schmitt Trigger input when configured in RC oscillator mode and a CMOS input otherwise.
4: This buffer is a Schmitt Trigger input when configured as the external interrupt.
5: This buffer is a Schmitt Trigger input when used in serial programming mode.
6: 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).

Description
PORTD can be a bi-directional I/O port or parallel slave port
for 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.
RE1 can also be write control for the parallel slave port.
RE2 can also be select control for the parallel slave port.
