Bit
Device Status (DS) — R/W. System software sets this bit for SATA queuing operations
prior to setting the PxCI.CI bit in the same command slot entry. This field is cleared via
the Set Device Bits FIS.
This field is also cleared when PxCMD.ST (ABAR+118h/198h/218h/298h:bit 0) is
cleared by software, and as a result of a COMRESET or SRST.
Commands Issued (CI) — R/W. This field is set by software to indicate to the ICH8
that a command has been built-in system memory for a command slot and may be sent
to the device. When the ICH8 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. Bits in
this field shall only be set to 1 by software when PxCMD.ST is set to 1.
This field is also cleared when PxCMD.ST (ABAR+118h/198h/218h/298h:bit 0) is
cleared by software.
