3.1
The program memory can be erased with the Bulk
Erase Program Memory command.
To perform a Bulk Erase of the program memory, the
following sequence must be performed:
1.
2.
3.
If the address is pointing to the configuration memory
(0x2000-0x200F), then both user ID locations and
program memory will be erased.
