Legend:
R = Readable bit
W = Writable bit
U = Unimplemented bit, read as ‘0’
-n = Value at POR
‘1’ = Bit is set
‘0’ = Bit is cleared
x = Bit is unknown
bit 7
WRTD: Data EEPROM Write Protection bit
1
= Data EEPROM not write-protected
0
= Data EEPROM write-protected
bit 6
WRTB: Boot Block Write Protection bit
1
= Boot block (000000-007FFF, 000FFF or 001FFFh
) not write-protected
0
= Boot block (000000-007FFF, 000FFF or 001FFFh
) write-protected
bit 5
WRTC: Configuration Register Write Protection bit
1
= Configuration registers (300000-3000FFh) not write-protected
0
= Configuration registers (300000-3000FFh) write-protected
bit 4-0
Unimplemented: Read as ‘0’
Note 1:
Boot block size is determined by the BBSIZ<1:0> bits in CONFIG4L.
2:
This bit is read-only in normal execution mode; it can be written only in Program mode.
