bit 0
EBTR2: Table Read Protection bit(1,2,3)
1= Block 2 is not protected from table reads executed in other blocks
0= Block 2 is protected from table reads executed in other blocks
EBTR1: Table Read Protection bit(2,3)
1= Block 1 is not protected from table reads executed in other blocks
0= Block 1 is protected from table reads executed in other blocks
EBTR0: Table Read Protection bit(2,3)
1= Block 0 is not protected from table reads executed in other blocks

Note 1: Unimplemented in PIC18F2331/4331 devices; maintain this bit set.
2: Refer to Figure 23-5 for block boundary addresses.
3: Enabling the corresponding CPx bit is recommended to protect the block from external read operations.
