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.

As shown in Figure 2-7, 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 code memory,
data EEPROM, ID locations and Configuration bits can
be accessed and programmed in serial fashion.
Figure 2-8 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.
