1.4.3
One of the important features of the MCP4725 device is non-volatile memory. When
the device is first powered up, it outputs an analog voltage corresponding to the data
in the EEPROM. The user can confirm this feature using the following procedures:
1. Program the EEPROM memory. Refer to Section 1.4.2.2 “Saving the Script
2. Remove power (V
3. Connect power (V
4. You can confirm the V
1.4.4
You can read back the DAC code stored in the DAC register with the following steps:
1. Create a read command script file name as shown below and execute it.
2. The results (DAC code) will appear on the PICkit™ Serial Transactions page.
