— = unimplemented, read as ‘0’. Shaded cells are not used during ECCP operation.
The SBOREN bit is only available when the BOREN<1:0> Configuration bits = 01; otherwise, it is disabled and
reads as ‘0’. See Section 5.4 “Brown-out Reset (BOR)”.
These registers and/or bits are unimplemented on 28-pin devices; always maintain these bits clear.
