WRT2: Write Protection bit⁽¹⁾
1 = Block 2 (004000-005FFFh) not write protected
0 = Block 2 (004000-005FFFh) write protected
WRT1: Write Protection bit
1 = Block 1 (002000-003FFFh) not write protected
0 = Block 1 (002000-003FFFh) write protected
WRT0: Write Protection bit
1 = Block 0 (000200h-001FFFh) not write protected
0 = Block 0 (000200h-001FFFh) write protected
Note 1: Unimplemented in PIC18FX439 devices; maintain this bit set.
