The STS word is used as follows:
Bit 15 to 8 just mirrors the corresponding bits in the CMD word.
The bits named s7 to s0 represents the status code that PowerMACS returns after executing the
command. They should be interpreted as a signed 8 bit value where a value greater or equal to zero
indicates a positive result, and negative values a failure. Currently the following status codes are defined:
Illegal process data specified
Illegal size of the process data area
Device is not properly connected
Received setup is too big
Size of Data bytes In to small for the requested service
Size of Data bytes Out to small for the requested service
The specified Process Data type cannot be flushed/skipped
