REGISTERS
All 6 parameters above must be listed in order. The parameters with * are
not modifiable. The MCP4728 device on the evaluation board has I
address bits (A2, A1, A0) = (0,0,0).
At this point, the PICkit Serial Analyzer transmits the I
to the MCP4728 device. The saved file name will appear in the Users I2C
Scripts column, and can be re-used any time by selecting the file name.
When you click on the “Execute Script” menu, the “Busy” LED on the PICkit
Serial Analyzer will momentarily turn on and then turn off. If the LED
remains ON, a communications problem has occurred. Remove the PICkit
Serial Analyzer from your computer and recheck the parameter values,
including the order of parameters under the “Script Detail” column including
the I
immediately after sending the I

C address of the device, and try again until the “Busy” LED turns OFF
--------> This means there are two bytes to send.
--------> 1’st byte (000-0000) selecting external V
--------> Address byte = 1100-0000 (See Note).
