1. Type in any script name (i.e., MCP4728_W_SeqB) in the space below the Script
2. Click Save Script button.
3. Click Execute Script button.
4. You can also see the SCL and SDA waveforms using the Oscilloscope.
5. Read the V
Since the UDAC bit is set to “0” in the command, the device will update the V
and D outputs as soon as the command is executed regardless of the condition of the
LDAC pin switch S1.

REGISTERS
All parameters above must be listed in order. The parameter above 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 transmits the I
MCP4728 device. The saved file name will appear in 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
