Figure 2-7 shows the high-level overview of the
programming process. First, a Bulk Erase is performed.
Next, the code memory, ID locations and data
EEPROM are programmed (see Section 3.3 “Data
EEPROM Programming”). These memories are then
verified to ensure that programming was successful. If
no errors are detected, the Configuration bits are then
programmed and verified.

ory, data EEPROM (see Section 3.3 “Data EEPROM
Programming”), ID locations and Configuration bits
can be accessed and programmed in serial fashion.
Figure 2-9 shows the exit sequence.
The sequence that enters the device into the Program/
Verify mode places all unused I/Os in the high-impedance
state.
