bit 0
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 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 PIC16(L)F1938. Read as ‘0’.
