The System Status Word returned is made up of 8 hexadecimal digits. To decode this word, convert each digit into a
4-digit binary number. (
Table 24 is provided as an aid.) Follow the example below:
Each binary digit (bit) represents a flag that is either 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.
Table 25 contains a list of the lower 16 status flags that will be useful for fault finding. The upper 16 status flags are
reserved by Edwards.
