6.1.2 Response to COMRESET

The response to COMRESET is almost the same as the response when power is turned on and a power-on reset is then cancelled. The device establishes communication with the SATA interface (PHY Ready) and sends the Register DH FIS (STS = 50h) to notify the host that the device is ready. Then, the COMRESET sequence is completed.
