bit 0
Legend:
R = Readable bit
-n = Value at POR
W = Writable bit
‘1’ = Bit is set
U = Unimplemented bit, read as ‘0’
‘0’ = Bit is cleared
x = Bit is unknown
bit 7-4
bit 3-0
Unimplemented: Read as ‘0’
RE<3:0>: PORTE I/O Pin bits⁽¹⁾
1 = Port pin is > VIH
0 = Port pin is < VIL
Note 1: RE<2:0> are not implemented on the PIC16F722/723/726/PIC16LF722/723/726. Read as ‘0’.

TRISE3: RE3 Port Tri-state Control bit
This bit is always ‘1’ as RE3 is an input only
TRISE<2:0>: RE<2:0> Tri-State Control bits⁽¹⁾
1 = PORTE pin configured as an input (tri-stated)
0 = PORTE pin configured as an output
Note 1: TRISE<2:0> are not implemented on the PIC16F722/723/726/PIC16LF722/723/726. Read as ‘0’.
