RUC
NOP (does not affect current state of the unit)
Start execution of the first command on the CBL If a command is executing
complete it before starting the new CBL The beginning of the CBL is in CBL
OFFSET (address)
Resume the operation of the Command Unit by executing the next command
This operation assumes that the Command Unit has been previously sus-
pended
Suspend execution of commands on CBL after current command is complete
Abort current command immediately
Loads the Bus Throttle timers so they will be initialized with their new values
