PIC16(L)F720/721

8.2 Code Protection

If the code protection bit(s) have not been

programmed, the on-chip program memory can be

read out using ICSP™ for verification purposes.

Note:

The entire Flash program memory will be

erased when the code protection is turned

off. See the “PIC16(L)F720/721 Memory

Programming Specification” (DS41409)

for more information.

8.3 User ID

Four memory locations (2000h-2003h) 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. See the

“PIC16(L)F720/721 Memory Programming Specifica-

tion” (DS41409) for more information.
