Faults Instrument - Scopy SWIOT1L plugin
The Faults Instrument represents the diagnostic operation performed on the AD-SWIOT1L-SL device, more accurately the AD74413R and MAX14906 chips. The numeric value from each device is extracted from specific registers and each bit represents a potential error or information about the chip.
For more information on the faults meaning, consider checking the corresponding datasheets.

6. Faults Explanations
Each fault is explained in this section. The first 4 faults from AD74413R (VI_ERR_A, VI_ERR_B, VI_ERR_C and VI_ERR_D) have special meanings based on the configuration of the channel. Only one of them will be shown when a specific function is selected and all of them when no specific function is selected.
The explanations are highlighted for the faults that have the active bit set (i.e.
were active on the last read).
Each fault has 3 sections:
Stored Bit section: The stored bit represents whether that specific fault has been active twice consecutively, making it a persistent (stored) bit. This can be cleared using the RESET STORED button.
Active Bit section: The active bit represents the value that was last read from the device.
Bit index: The index bit is a notation for identifying faults. It does not represent the fault name. The name can be seen by hovering over the fault or by checking the “Faults Explanation” area corresponding to the index.
