4.1.4.1 Load Configuration
The Load Configuration command is used to access
the Configuration Word (0x2007), User ID (0x2000-
0x2003) and Calibration Word (0x2008). This
command sets the PC to address 0x2000 and loads the
data latches with one word of data.
To access the configuration memory, send the Load
Configuration command. Individual words within the
configuration memory can be accessed by sending
Increment Address commands and using load or read
data for program memory.
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 the Stop bit (see Figure 4-4).
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 (VIL).
