Port E is an 8-bit input-only port. In addition to their input capability, port E pins are shared with
A/D functions, as shown in the following table.
On reset the pins are configured as general purpose high-impedance inputs.
4.5.1
This is a read-only register and is not affected by reset. The bits may be read at any time.

Port E data (PORTE)
As port E shares pins with the A/D converter, a read of this register may affect any
conversion currently in progress, if it coincides with the sample portion of the
conversion cycle. Hence, normally port E should not be read during the sample portion
of any conversion.
