5.5 Power-on and COMRESET

Figure 5.17 shows the power-on sequence, and Figure 5.18 shows the COMRESET
sequence.
Immediately after power-on or COMRESET, the host sets 0x7Fh in the Status field
of the Shadow Block Register and 0xFFh in other fields. After the power-on
sequence shown below and after communication with the SATA interface is
established, the host sets 0xFFh in the Status field of the Shadow Block Register.
The device completes the power-on sequence within 10 ms so that communication
with the SATA interface can be established.
