bit 7 bit 0
bit 7 Unimplemented: Read as ‘0’
bit 6 EBTRB: Boot Block Table Read Protection bit
For PIC18FX520 devices:
1 = Boot Block (000000-0007FFh) not protected from table reads executed in other blocks
0 = Boot Block (000000-0007FFh) protected from table reads executed in other blocks
For PIC18FX620 and PIC18FX720 devices:
1 = Boot Block (000000-0001FFh) not protected from table reads executed in other blocks
0 = Boot Block (000000-0001FFh) protected from table reads executed in other blocks
bit 5-0 Unimplemented: Read as ‘0’
Legend:
