PORTE is a bi-directional I/O port.
25 I/O ST/TTL(3)
RE0 can also be read control for the parallel slave
port, or analog input5.
26 I/O ST/TTL(3)
RE1 can also be write control for the parallel slave
port, or analog input6.
27 I/O ST/TTL(3)
RE2 can also be select control for the parallel slave
port, or analog input7.
VSS

P
— Ground reference for logic and I/O pins.
VDD
11,32 12,35 7,28
P
— Positive supply for logic and I/O pins.
NC
— 1,17,28, 12,13,
— These pins are not internally connected. These pins
40 33,34
should be left unconnected.
Legend: I = input
O = output
— = Not used
I/O = input/output
TTL = TTL input
P = power
ST = Schmitt Trigger input
Note 1: This buffer is a Schmitt Trigger input when configured as an external interrupt.
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 general purpose I/O and a TTL input when used in the Parallel
Slave Port mode (for interfacing to a microprocessor bus).
4: This buffer is a Schmitt Trigger input when configured in RC oscillator mode and a CMOS input otherwise.
