10.2

Code Protection

Code protection is controlled using the CP bit in

Configuration Word 1. When code protection is

enabled, all program memory locations (0000h-7FFFh)

read as all ‘0’. Further programming is disabled for the

program memory (0000h-7FFFh).

Data memory is protected with its own Code-Protect bit

(CPD). When data code protection is enabled (CPD = 0),

all data memory locations read as ‘0’. Further

programming is disabled for the data memory. Data

memory can still be programmed and read during

program execution.

The user ID locations and Configuration Words can be

programmed and read out regardless of the code

protection settings.

10.3

User ID

Four memory locations (8000h-8003h) are designated

as ID locations where the user can store checksum or

other code identification numbers. These locations are

not accessible during normal execution, but are read-

able and writable during Program/Verify mode. Only

the Least Significant 7 bits of the ID locations are

reported

when

using

MPLAB®

IDE.
