Description
Returns an integer which, when translated to binary, indicates the state of all bits in the
device fault register for the device specified. A bit set as 1 indicates a TRUE condition.
If a bit of any device fault register is TRUE, the device fault bit of associated Slot fault
register will have corresponding bit set TRUE.
Important:
• Reserved (unused) bits are returned with value 0.
• Device without a fault register will return a value 0.
