Write only: Commands and their parameters are written to the Command
and Parameter Registers. See “ Register-Based Command Reference”
starting on page 356.

Note
The parameters associated with a command must always be written before
the actual command op code. No command requires more than three
parameter words. Upon a write to the Command Register, the Cmd/Parm
Ready bit is de-asserted (set LOW). It is subsequently asserted after the
control processor has removed the command word and associated
parameters from the Parameter Register buffers and is ready to receive
another command.
Scan and Card Control Registers
Scan Status and Control Register
Base + 10
16
Read/Write: This register controls and provides status of the execution of
scan lists. Note that bits 15 through 8 are read-only and are used to report scan
status, and bits 7 through 0 are read/write and are used to control the scan.
