Figure 2-3 shows the high level overview of the
programming process. The device is first checked to
see if it is blank; if it is not, a bulk erase is performed.

Next, the code memory, ID locations, and data
EEPROM are programmed. These memories are then
verified to ensure that programming was successful. If
no errors are detected, the configuration bits are then
programmed and verified.
