Figure 1-12 shows an example of writing a script file on PICkit Serial PC GUI for a Fast
Write Command. This command writes to the DAC input registers and power-down
selection bits. The data are sent sequentially from channel A to the channel D.
EEPROM is not affected. This device updates the DAC output registers (V
