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 4.4 “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 2.6.4 “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.
