Port E general-purpose input/output data—Data Register
When not used with an alternative signal, this pin can be used as general-purpose I/O.
In general-purpose output mode the port data register bit is driven to the pin.
If the associated data direction bit of this pin is set to 1, a read returns the value of the port register, otherwise the
buffered pin input state is read.
Port E Data Direction—
This bit determines whether the associated pin is an input or output.
