Commands Issued (CI) — R/W. This field is set by software to indicate to the Intel
ICH7 that a command has been built-in system memory for a command slot and may
be sent to the device. When the ICH7 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.
