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
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.
