The SBOREN bit is only available when the BOREN1:BOREN0 configuration bits = 01; otherwise, it is disabled and reads as ‘0’. See
Section 4.4 “Brown-out Reset (BOR)”.
These registers and/or bits are not implemented on 28-pin devices and are read as ‘0’. Reset values are shown for 40/44-pin devices;
individual unimplemented bits should be interpreted as ‘-’.
The PLLEN bit is only available in specific oscillator configuration; otherwise it is disabled and reads as ‘0’. See Section 2.6.4 “PLL in
INTOSC Modes”.
The RE3 bit is only available when Master Clear Reset is disabled (MCLRE configuration bit = 0). Otherwise, RE3 reads as ‘0’. This bit is
read-only.
RA6/RA7 and their associated latch and direction bits are individually configured as port pins based on various primary oscillator modes.
When disabled, these bits read as ‘0’.
Bit 7 and bit 6 are cleared by user software or by a POR.
