x = unknown, u = unchanged, - = unimplemented, q = value depends on condition. Shaded cells are unimplemented, read as ‘0’.
Bit 21 of the TBLPTRU allows access to the device Configuration bits.
The SBOREN bit is only available when BOREN<1:0> = 01; otherwise, the bit reads as ‘0’.
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 ‘-’.
RA6 is configured as a port pin based on various primary oscillator modes. When the port pin is disabled, all of the associated bits read ‘0’.
RE3 is only available as a port pin when the MCLRE Configuration bit is clear; otherwise, the bit reads as ‘0’.
RC5 and RC4 are only available as port pins when the USB module is disabled (UCON<3> = 0).
