Depending on the particular PIC18F2450/4450 device
selected, PORTE is implemented in two different ways.
For 40/44-pin devices, PORTE is a 4-bit wide port.
Three pins (RE0/AN5, RE1/AN6 and RE2/AN7) are
individually configurable as inputs or outputs. These
pins have Schmitt Trigger input buffers. When selected
as an analog input, these pins will read as ‘0’s.
The corresponding Data Direction register is TRISE.
Setting a TRISE bit (= 1) will make 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., put the contents of the output latch on the selected
pin).
TRISE controls the direction of the RE pins, even when
they are being used as analog inputs. The user must
make sure to keep the pins configured as inputs when
using them as analog inputs.
The Output Latch register (LATE) is also memory
mapped. Read-modify-write operations on the LATE
register read and write the latched output value for
PORTE.
The fourth pin of PORTE (MCLR/V
only pin. Its operation is controlled by the MCLRE Config-
uration bit. When selected as a port pin (MCLRE = 0), it

implemented only when Master Clear functionality is disabled (MCLRE Configuration bit = 0); otherwise,
read as ‘0’.
RE3 is the only PORTE bit implemented on both 28-pin and 40/44-pin devices. All other bits are
implemented only when PORTE is implemented (i.e., 40/44-pin devices).
Unimplemented in 28-pin devices; read as ‘0’.
On a Power-on Reset, RE2:RE0 are
configured as analog inputs.

functions as a digital input only pin; as such, it does not
have TRIS or LAT bits associated with its operation.
Otherwise, it functions as the device’s Master Clear input.
In either configuration, RE3 also functions as the
programming voltage input during programming.
EXAMPLE 9-5:
9.5.1
For 28-pin devices, PORTE is only available when
Master Clear functionality is disabled (MCLRE = 0). In
these cases, PORTE is a single bit, input only port
comprised of RE3 only. The pin operates as previously
described.
