This bit is read-only in normal execution mode; it can be written only in Program mode.
Unimplemented: Read as ‘0’
WRT1: Write Protection bit
1 = Block 1 (002000-003FFFh) is not write-protected
0 = Block 1 (002000-003FFFh) is write-protected
WRT0: Write Protection bit
1 = Block 0 (000800-001FFFh) or (001000-001FFFh) is not write-protected
0 = Block 0 (000800-001FFFh) or (001000-001FFFh) is write-protected
Unimplemented: Read as ‘0’
WRTB: Boot Block Write Protection bit
1 = Boot block (000000-0007FFh) or (000000-000FFFh) is not write-protected
0 = Boot block (000000-0007FFh) or (000000-000FFFh) is write-protected
WRTC: Configuration Register Write Protection bit
1 = Configuration registers (300000-3000FFh) are not write-protected
