2.3.1.9
After this command is performed and Calibration bits are
erased, the entire program memory is erased. If data is
code-protected, data memory will also be erased.
To perform a bulk erase of the program memory, the
following sequence must be performed.

3.
4.
5.
If the address is pointing to the ID/configuration
program memory (0x2000-0x201F), then both the user
memory and the ID locations will be erased.
