PORTE is a 8-bit wide, bidirectional port. The

corresponding PORTE pin an input (i.e., put the
corresponding output driver in a High-Impedance mode).
Clearing a TRISE bit (= 0 ) will make the corresponding
PORTE pin an output (i.e., enable the output driver and
put the contents of the output latch on the selected pin).
Example 12-1
Reading the PORTE register
status of the pins, whereas writing to it will write to the
PORT latch. All write operations are read-modify-write
operations. Therefore, a write to a port implies that the
port pins are read, this value is modified and then written
to the PORT data latch (LATE).
The TRISE register
pin output drivers, even when they are being used as
analog inputs. The user should ensure the bits in the
TRISE register are maintained set when using them as
analog inputs. I/O pins configured as analog input always
read ‘ 0 ’.
12.6.1
The ANSELE register
configure the Input mode of an I/O pin to analog.
Setting the appropriate ANSELE bit high will cause all
digital reads on the pin to be read as ‘ 0 ’ and allow
analog functions on the pin to operate correctly.
The state of the ANSELE bits has no effect on digital out-
put functions. A pin with TRIS clear and ANSELE set will
still operate as a digital output, but the Input mode will be
analog. This can cause unexpected behavior when exe-
cuting read-modify-write instructions on the affected
port.

12.6.2
Each PORTE pin is multiplexed with other functions. The
pins, their combined functions and their output priorities
are shown in
When multiple outputs are enabled, the actual pin
control goes to the peripheral with the highest priority.
Analog input and some digital input functions are not
included in the list below. These input functions can
remain active when the pin is configured as an output.
Certain digital input functions override other port
functions and are included in
