— — — — — —WRT1WRT0
bit 7 bit 0
Legend:
R = Readable bit C = Clearable bit U = Unimplemented bit, read as ‘0’
-n = Value when device is unprogrammed u = Unchanged from programmed state
bit 7-2 Unimplemented: Read as ‘0’
bit 1 WRT1: Write Protection bit (Block 1 Code Memory Area)
1 = Block 1 is not write-protected
0 = Block 1 is write-protected
bit 0 WRT0: Write Protection bit (Block 0 Code Memory Area)
1 = Block 0 is not write-protected
0 = Block 0 is write-protected

-n = Value when device is unprogrammed u = Unchanged from programmed state
bit 7 WRTD: Write Protection bit (Data EEPROM)
1 = Data EEPROM is not write-protected
0 = Data EEPROM is write-protected
bit 6 WRTB: Write Protection bit (Boot Block Memory Area)
1 = Boot Block is not write-protected
0 = Boot Block is write-protected
bit 5 WRTC: Write Protection bit (Configuration Registers)
(1)
1 = Configuration registers are not write-protected
0 = Configuration registers are write-protected
bit 4-0 Unimplemented: Read as ‘0’
Note 1: This bit is read-only in normal execution mode; it can be written only in Program mode.
