This command gets the actual running mode
from the SAA6752HS and is read-only. The
busy flag indicates that the SAA6752HS is
working at a control command. If the busy flag
is set, the SAA6752HS skips all received

masking of events; see Table 11
This command allows reading a status
register. Reading the status will clear the
status and reset the interrupt assertion pin.
This command allows reading of the current
MIPS firmware version number, hardware
number and the audio DSP firmware number.
Each number contains 4 bytes.
