bit 7 bit 0

Legend:

R = Readable bit C = Clearable bit U = Unimplemented bit, read as ‘0’

-n = Value when device is unprogrammed bit u = Unchanged from programmed state

bit 7-1 Unimplemented: Read as ‘0

bit 0 EBTR: Table Read Protection bit

(2,3)

1= Internal program memory block is not protected from table reads executed from external memory

block

0= Internal program memory block is protected from table reads executed from external memory block

Note 1: Unimplemented on PIC18F6310/6410 devices; maintain the bit set.

2: Valid for the entire internal program memory block in Extended Microcontroller mode and for only the boot

block (0000h to 07FFh) in Microcontroller with Boot Block mode. This bit has no effect in Microcontroller

and Microprocessor modes.

3: It is recommended to enable the CP bit to protect the block from external read operations.
