24.5
The overall structure of the code protection on the
PIC18F6310/6410/8310/8410 Flash devices differs
from previous PIC18 devices.
For all devices in the PIC18FX310/X410 family, the
user program memory is made of a single block.
Figure 24-5
for individual devices. Code protection for this block is
controlled by a single bit, CP (CONFIG5L<0>). The CP
bit inhibits external reads and writes; it has no direct
effect in normal execution mode.
24.5.1
The program memory may be read to any location
using the table read instructions. The Device ID and the
Configuration registers may be read with the table read
instructions.
For devices with the external memory interface, it is
possible to execute a table read from an external
program memory space and read the contents of the
on-chip memory. An additional code protection bit,

EBTR (CONFIG7L<0>), is used to protect the on-chip
program memory space from this possibility. Setting
EBTR prevents table read commands from executing
on any address in the on-chip program memory space.
EBTR is implemented only on devices with the external
memory interface. Its operation also depends on the
particular mode of operation selected. In Extended
Microcontroller mode, programming EBTR enables
protection from external table reads for the entire
program memory. In Microcontroller with Boot Block
mode, only the first 2 Kbytes of on-chip memory (000h
to 7FFh) are protected. This is because, only this range
of internal program memory is accessible by the
microcontroller in this operating mode.
When the device is in Micrcontroller or Microprocessor
modes, EBTR has no effect on code protection.
24.5.2
The Configuration registers can only be written via
ICSP using an external programmer. No separate
protection bit is associated with them.
