Note 1:

This bit is available when Master Clear is disabled (MCLRE = 0). When MCLRE is set, the bit is unimplemented.

Unimplemented on 64-pin devices (PIC18F6XK22), read as ‘0’.

Unimplemented on devices with a program memory of 32 Kbytes (PIC18FX5K22).

Note

This is not a physical register.

Unimplemented on 64-pin devices (PIC18F6XK22), read as ‘0’.

This register is not available on devices with a program memory of 32 Kbytes (PIC18FX5K22).

Addresses, F16h through F5Fh, are also used by SFRs, but are not part of the Access RAM. To access these registers,
users must always load the proper BSR value.
