Legend: x = unknown, u = unchanged, — = unimplemented, q = value depends on condition
Note 1: The SBOREN bit is only available when the BOREN<1:0> Configuration bits = 01; otherwise it is disabled and reads as ‘0’. See
Section 4.4 “Brown-out Reset (BOR)”.
2: 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 ‘-’.
3: The PLLEN bit is only available in specific oscillator configuration; otherwise it is disabled and reads as ‘0’. See Section 2.6.2 “PLL in
HFINTOSC Modes”.
4: 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.
5: 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’.
6: All bits of the ANSELH register initialize to ‘0’ if the PBADEN bit of CONFIG3H is ‘0’.
7: This register is only implemented in the PIC18F46K20 and PIC18F26K20 devices.
