6.1 Reset and Diagnosis
This section explains the device responses to power-on and an accepted reset.
6.1.1 Response to power-on
Immediately after power is turned on, the host sets 0x7Fh in the Status field of the
Shadow Block and 0xFFh in other fields. After communication with the SATA
interface is established, the host sets 0xFFh in the Status field of the Shadow
Block. The device establishes communication with the SATA interface (PHY
Ready) within 10 ms. The device sends the FIS (STS = 50h) to notify the host
that the device is ready.
Note: Figure 6.1 assumes that power is turned on after the power-off state
continued for more than five seconds.
