2.3.1.1 Load Configuration
After receiving this command, the Program Counter
(PC) will be set to 0x2000. Then, by applying 16 cycles
to the clock pin, the chip will load 14 bits in a data word,
as described above, which will be programmed into the
configuration memory. A description of the memory
mapping schemes of the program memory for normal
operation and Configuration mode operation is shown in
Figure 2-3. After the configuration memory is entered,
the only way to get back to the user program memory is
to exit the Program/Verify mode by taking MCLR
low
(V
IL).

2.3.1.2 Load Data For Program Memory
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 command is shown in Figure 2-4.
