1.3.2.14
The device will upload the EEPROM data to both input and output DAC registers (a)
during power-up sequence or (b) when it receives the General Call Reset command.
One of these conditions makes the analog outputs available immediately with their
current EEPROM settings. Note that the Power-Down bit must be cleared for the
output.
• Testing Procedure:
a. Write to the EEPROM with one of the examples shown earlier (i.e.,
b. Measure and record the analog voltage of each channel (V
c. Turn-off the V
d. Turn-back on the V
1.3.2.15
This example shows how to read back the DAC input registers and EEPROM data.
Figure 1-20 shows the PICkit Serial script file to read all DAC input registers and
EEPROM data. Once this file is executed, the PC GUI will show you the contents of the
registers and EEPROM.
