Port E is a standard 8-bit bidirectional port.
The port E data register (PTE) contains a data latch for each of the eight
port E pins.
PTE[7:0] — Port E Data Bits
Data direction register E (DDRE) determines whether each port E pin is
an input or an output. Writing a logic 1 to a DDRE bit enables the output
buffer for the corresponding port E pin; a logic 0 disables the output
buffer.

These read/write bits are software-programmable. Data direction of
each port E pin is under the control of the corresponding bit in data
direction register E. Reset has no effect on port E data.
