2.4
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. These memories are then
verified to ensure that programming was successful. If
no errors are detected, the Configuration bits are then
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, data EEPROM, 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.
2.5.1
When the LVP Configuration bit is ‘1’ (see Section 5.3
“Low-Voltage Programming (LVP) Bit”), the Low-
Voltage ICSP mode is enabled. Low-Voltage ICSP
Program/Verify mode is entered by holding PGC and
PGD low, placing a logic high on PGM and then raising
MCLR/V
dedicated to the programming function and ceases to
be a general purpose I/O pin.
The sequence that enters the device into the Program/
Verify mode places all unused I/Os in the high-impedance
state.
