bit 7

bit 0

Legend:

R = Readable bit

W = Writable bit

U = Unimplemented bit, read as ‘0’

u = Bit is unchanged

x = Bit is unknown

-n/n = Value at POR and BOR/Value at all other Resets

‘1’ = Bit is set

‘0’ = Bit is cleared

bit 7-4

Unimplemented

: Read as ‘0’

bit 3-0

RE<3:0>

: PORTE I/O Pin bits(1)

= Port pin is > VIH

= Port pin is < VIL

Note 1:

RE<2:0> are not implemented on the PIC16(L)F1516/8. Read as ‘0’. Writes to RE<2:0> are actually writ-

ten to corresponding LATE register. Reads from PORTE register is the return of actual I/O pin values.

TRISE<2:0>:

RE<2:0> Tri-State Control bits(1)

= PORTE pin configured as an input (tri-stated)

= PORTE pin configured as an output

Note 1:

TRISE<2:0> are not implemented on the PIC16(L)F1517/9. Read as ‘0’.

Unimplemented, read as ‘1’.
