Bit 21 of the PC is only available in Test mode and Serial Programming modes.
The SBOREN bit is only available when CONFIG2L<1:0> = 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 PIC18F2682/2685 devices and are read as ‘0’. Reset values are shown for PIC18F4682/4685
devices; individual unimplemented bits should be interpreted as ‘—’.
The PLLEN bit is only available in specific oscillator configurations; 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 (CONFIG3H<7> = 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’.
CAN bits have multiple functions depending on the selected mode of the CAN module.
This register reads all ‘0’s until the ECAN™ technology is set up in Mode 1 or Mode 2.
These registers and/or bits are available on PIC18F4682/4685 devices only.
