Unimplemented: Read as ‘0’
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:
R = Readable bit
- n = Value when device is unprogrammed
P = Programmable bit U = Unimplemented bit, read as ‘0’
u = Unchanged from programmed state
