2.4
Figure 2-8 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 Chip Erase is performed.
Next, the code memory and ID locations are
programmed. These memories are then verified to
ensure that programming was successful. If no errors
are
programmed and verified.
2.5
The High-Voltage ICSP Program/Verify mode is
entered by holding PGC and PGD low and then raising
MCLR/V
the code memory, ID locations and configuration bits
can be accessed and programmed in serial fashion.
The sequence that enters the device into the
Program/Verify mode places all unused I/Os in the
high-impedance state.
