CCS/PGA411-Q1: SPI communication is fine, but reading SFAULT in DEV_STAT4 indicates a fault, but no other registers show a specific fault, and a man-made fault will not report a specific fault

    Hi,

    Is the device in FAULT mode? Can you monitor FAULTRES pin? If this pin is pull up high, then there is a fault in the system. Please note that fault flags will be cleared upon a SPI read command (assuming the fault itself is no longer present in the system). 

    To clear the fault state in the system, when all fault conditions have been removed the FAULTRES pin must be toggled (high-low-high) and the PGA411-Q1 device transitions back into normal mode of operation.

    Regards

    Sharath.
