Each binary digit (bit) represents a flag that is active (state 1) or not active (state 0). To
help decode the System Status Word, each bit is numbered (starting with 0 for the least
significant to 31 for the most significant) as shown below.
Refer to
for the list of the lower 16 status flags that are useful for fault
finding. The upper 16 status flags are reserved by us.
