PORTD is a bidirectional I/O port, or a Parallel Slave
Port (PSP) for interfacing to a microprocessor port.
These pins have TTL input buffers when the PSP
module is enabled.
PORTE is a bidirectional 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. They
should be left unconnected.
