WRTD: Data EEPROM Write Protection bit
1 = Data EEPROM not write protected
0 = Data EEPROM write protected
WRTB: Boot Block Write Protection bit
For PIC18FX520 devices:
1 = Boot Block (000000-0007FFh) not write protected
0 = Boot Block (000000-0007FFh) write protected
For PIC18FX620 and PIC18FX720 devices:
1 = Boot Block (000000-0001FFh) not write protected
0 = Boot Block (000000-0001FFh) write protected
WRTC: Configuration Register Write Protection bit⁽¹⁾
1 = Configuration registers (300000-3000FFh) not write protected
0 = Configuration registers (300000-3000FFh) write protected
Note 1: This bit is read only, and cannot be changed in User mode.
Unimplemented: Read as ‘0’
Legend:
R = Readable bit
P = Programmable bit
- n = Value when device is unprogrammed
U = Unimplemented bit, read as ‘0’
u = Unchanged from programmed state
