19.3.2.8.1
This HC_ON bit in HControl allows the host software to bring the SATA controller online or offline. The
SATA controller online status should only be changed when there are no commands queued in the SATA
controller or at any attached device.
When the host application wishes to bring the SATA controller offline it clears the HC_ON control bit.
This acts as a request to the SATA controller to go offline. The SATA controller will signal it has completed
this operation by clearing the HS_ON bit in the HStatus register. If any commands are outstanding at SATA
controller or device then the SATA controller will wait for the operation to complete before going offline.
It the host application wishes to bring the SATA controller offline regardless of the queue status, it clears
the HC_ON bit while the HS_OFF bit of the HStatus register is set.
When the host application wishes to bring the SATA controller online, it sets the HC_ON control bit. This
acts as a request to the SATA controller to go online. The SATA controller will signal it has completed this
operation by setting to 1 the HS_ON status bit.
19.3.2.9
When queuing a command into the SATA controller, the CQPMP, shown in
the value of the PMP field that addresses the device to which the command will be issued. If the device is
directly attached (that is, there is no port multiplier in the system), then this register is not required and
should be cleared.
