Legend:
Note 1: This buffer is a Schmitt Trigger input when configured as the external interrupt.
SS
DD
2: This buffer is a Schmitt Trigger input when used in serial programming mode.
3: This buffer is a Schmitt Trigger input when configured as a general purpose I/O and a TTL input when used
in the Parallel Slave Port Mode (for interfacing to a microprocessor port).

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.
Not Connected.
P = power
ST = Schmitt Trigger input
RE0/RD read control for parallel slave port.
RE1/WR write control for parallel slave port.
RE2/CS select control for parallel slave port.
