PGA Error Indicators Tab
The error indicators for the PGA280 can be seen on the PGA Error Indicator tab (shown in
).
There are seven indicator lights that show error conditions in the PGA280.
Figure 37. PGA Error Indicators Tab
Each error corresponds to a bit in the error register (register 4) of the PGA280. At the top of the tab, a
pull-down menu selects the suppression time for the error flags. In the PGA280 data sheet, this period is
referred to as FLAGTIM and can be found in register 11.
The Update Errors button clears the error register and updates the status of the error indicators on this
tab. Note that as the device powers up for the first time, these error flags may be set. If you are going to
use these flags, it is important to first clear them after the part has settled after start up.
