PIC16LF1904/6/7
11.5 PORTE Registers
RE3 is input only, and also functions as MCLR. The
MCLR feature can be disabled via a configuration fuse.
RE3 also supplies the programming voltage. The TRIS bit
for RE3 (TRISE3) always reads ‘1’.

PORTE FUNCTIONS AND OUTPUT
PRIORITIES
No output priorities, RE3 is an input only pin.

Legend:
R = Readable bit
u = Bit is unchanged
‘1’ = Bit is set
W = Writable bit
x = Bit is unknown
‘0’ = Bit is cleared
U = Unimplemented bit, read as ‘0’
-n/n = Value at POR and BOR/Value at all other Resets
bit 7-4
bit 3-0
Unimplemented: Read as ‘0’
RE<3:0>: PORTE Input Pin bit⁽¹⁾
1 = Port pin is > VIH
0 = Port pin is < VIL
Note 1: RE<2:0> are not implemented on the PIC16LF1906. Read as ‘0’. Writes to RE<2:0> are actually written to
the corresponding LATE register. Reads from the PORTE register is the return of actual I/O pin values.
