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
bit 3
Unimplemented: Read as ‘0’
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
bit 1
bit 0
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
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
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.
2: It is recommended to enable the corresponding CPx bit to protect the block from external read operations.
