Note 1: Bit 21 of the PC is only available in Test mode and Serial Programming modes.
2: The SBOREN bit is only available when CONFIG2L<1:0> = 01; otherwise, it is disabled and reads as ‘0’. See Section 5.4 “Brown-out Reset (BOR)”.
3: These registers and/or bits are not implemented on PIC18F2X80 devices and are read as ‘0’. Reset values are shown for PIC18F4X80 devices;
individual unimplemented bits should be interpreted as ‘—’.
4: The PLLEN bit is only available in specific oscillator configuration; otherwise, it is disabled and reads as ‘0’. See Section 3.6.4 “PLL in INTOSC
Modes”.
5: 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.
6: 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’.
7: CAN bits have multiple functions depending on the selected mode of the CAN module.
8: This register reads all ‘0’s until the ECAN™ technology is set up in Mode 1 or Mode 2.
9: These registers are available on PIC18F4X80 devices only.
