5.5 Power-on and COMRESET

Figure 5.20 shows the power-on sequence, and Figure 5.21 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.
