Table 04h (Table 01h in DS1859 Configuration), 82h: DAC0 Value
FACTORY DEFAULT:
MEMORY TYPE:
DAC values from 00h to FFh for DAC0 are stored here. Under normal operation, the LUTs automatically select the DAC setting
according to the values programmed into the corresponding LUT. This byte is updated automatically based on the current
temperature and is corresponding setting in the LUT.
Table 04h (Table 01h in DS1859 Configuration), 83h: DAC1 Value
FACTORY DEFAULT:
MEMORY TYPE:
DAC values from 00h to FFh for DAC1 are stored here. Under normal operation, the LUTs automatically select the DAC setting
according to the values programmed into the corresponding LUT. This byte is updated automatically based on the current
temperature and is corresponding setting in the LUT.
