3.1.6.1
The Load Configuration command is used to access
the Configuration Word (0x2007) and user ID (0x2000-
0x2003). This command sets the Program Counter
(PC) to address 0x2000 and loads the data latches with
one word of data.
After receiving a Load Configuration command, the
Configuration Word is accessed by performing an
Increment Address command seven times, to point the
PC to the Configuration Word. It can then be
programmed with the loaded data using a Begin
Programming command either internally or externally
timed.

3.1.6.2
After receiving this command, the chip will load in a
14-bit “data word” when 16 cycles are applied, as
described previously. A timing diagram for the Load
Data For Program Memory command is shown in
Figure 3-5.

After the 6-bit command is input, the ICSPCLK pin is
cycled an additional 16 times for the Start bit, 14 bits of
data and a Stop bit. See Figure 3-4 for more details.
After the configuration memory is entered, the only way
to get back to the program memory is to exit the
Program/Verify mode by taking MCLR low (V
