Description
Note 1: The Configuration bits can only be programmed indirectly by programming the Flash Configuration Word.
2: The Configuration bits are reset to ‘1’ only on VDD Reset; it is reloaded with the programmed value at any device Reset.
3: These bits are not implemented in PIC18F46J11 family devices.
4: Once this bit is cleared, all the Configuration registers which reside in the last page are also protected. To disable code
protection, perform an ICSP Bulk Erase operation.
