has been built-in system memory for a command slot and may be sent to the device. When the ICH6
receives a FIS which clears the BSY and DRQ bits for the command, it clears the corresponding bit
in this register for that command slot.
This field is also cleared when PxCMD.ST (ABAR+118h/198h/218h/298h:bit 0) is cleared by
software.
