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 7-4

Unimplemented: Read as ‘0’

bit 3

EBTR3: Table Read Protection bit(1,2)

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

bit 2

EBTR2: Table Read Protection bit(1,2)

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

bit 1

EBTR1: Table Read Protection bit(2)

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

bit 0

EBTR0: Table Read Protection bit(2)

1 = Block 0 (000800-001FFFh) not protected from table reads executed in other blocks

0 = Block 0 (000800-001FFFh) protected from table reads executed in other blocks

Note 1:

Unimplemented in PIC18FX480 devices; maintain this bit set.

It is recommended to enable the corresponding CPx bit to protect the block from external read operations.
