bit 7 bit 0
Legend:
R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’
-n = Value at POR ‘1’ = Bit is set ‘0’ = Bit is cleared x = Bit is unknown
bit 7-4 Unimplemented: Read as ‘0’
bit 3-0 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’.

TRISE0
(1)
bit 7 bit 0
Legend:
R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’
-n = Value at POR ‘1’ = Bit is set ‘0’ = Bit is cleared x = Bit is unknown
bit 7-4 Unimplemented: Read as ‘0’
bit 3 TRISE3: RE3 Port Tri-state Control bit
This bit is always ‘1’ as RE3 is an input only
bit 2-0 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’.
