When the pins are used for the alternate function the DDRE and PORTE register has to be set
according to the alternate function description.
PortE Data Register – PORTE
PortE Data Direction Register – DDRE
PortE Input Pins Address – PINE
The PortE Input Pins address – PINE – is not a register, and this address enables access to the
physical value on each PortE pin. When reading PORTE, the PortE Data Latch is read, and
when reading PINE, the logical values present on the pins are read.
