3.2.6.1
The Load Configuration command is used to access
the Configuration Words (0x2007-0x2008) 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 7 or 8 times to point the
PC to Configuration Word 0x2007 or 0x2008. It can
then be programmed with the loaded data using a
Begin Programming command either internally or
externally timed.

3.2.6.2
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, ICSPCLK pin is
cycled an additional 16 times for the Start bit, 14 bits of
data and a Stop bit (see Figure 3-4).
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
