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)”.
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 RA5 bit is only available when Master Clear Reset is disabled (MCLRE Configuration bit = 0); otherwise, RA5 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.
Reset condition of PWMEN bits depends on the PWMPIN Configuration bit of CONFIG3L.
This bit has no effect if the Configuration bit, WDTEN, is enabled.
