Figure 3-4 shows the high-level overview of the
programming process. First, a Bulk Erase is performed.
Next, the program Flash, 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.

Advance Information
3.3
As shown in Figure 3-6, the High-Voltage ICSP
Program/Verify mode is entered by holding PGC and
PGD low and then raising MCLR/V
(high voltage). Once in this mode, the program Flash,
data EEPROM, ID locations and Configuration bits can
be accessed and programmed in serial fashion.
Figure 3-7 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.
