EBTR3: Table Read Protection bit(1)

1 = Block 3 (006000-007FFFh) not protected from table reads executed in other blocks

0 = Block 3 (006000-007FFFh) protected from table reads executed in other blocks

EBTR2: Table Read Protection bit(1)

1 = Block 2 (004000-005FFFh) not protected from table reads executed in other blocks

0 = Block 2 (004000-005FFFh) protected from table reads executed in other blocks

EBTR1: Table Read Protection bit

1 = Block 1 (002000-003FFFh) not protected from table reads executed in other blocks

0 = Block 1 (002000-003FFFh) protected from table reads executed in other blocks

EBTR0: Table Read Protection bit

1 = Block 0 (000200-001FFFh) not protected from table reads executed in other blocks

0 = Block 0 (000200-001FFFh) protected from table reads executed in other blocks

Note 1: Unimplemented in PIC18FX48 devices; maintain this bit set.

Legend:

R = Readable bit

P = Programmable bit

-n = Value when device is unprogrammed

U = Unimplemented bit, read as ‘0’

u = Unchanged from programmed state
