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 (000200h-001FFFh) not protected from Table Reads executed in other blocks
0 = Block 0 (000200h-001FFFh) protected from Table Reads executed in other blocks
Note 1: Unimplemented in PIC18FX439 devices; maintain this bit set.
