5.4.3 PIO data-out command protocol

• WRITE MULTI (EXT) (FUA EXT)

• WRITE BUFFER

• SECURITY DISABLE PASSWORD

• SECURITY SET PASSWORD

• SET MAX UNLOCK

2) If an error remaining in the device prevents command execution, the device

sends the RegDH FIS with 1 set in the I bit.

Execution of the following commands involves data transfers from the host system

to the device:

• WRITE SECTOR (S) (EXT)

• WRITE VERIFY

• SMART WRITE LOG SECTOR

• SECURITY ERASE UNIT

• SECURITY UNLOCK

• SET MAX SET PASSWORD

• DOWNLOAD MICROCODE

• WRITE LOG EXT

• DEVICE CONFIGRATION SET

Data of one or more sectors is transferred from the host to the device.

An outline of this protocol is as follows:

1) The device receives a PIO data-out command with the RegHD FIS.

3) When the device is ready to receive data, it sets 0 in the BSY bit and 1 in the

DRQ bit of the Status field of the PIO Setup FIS. At this time, the device sets

0 in the I bit of the Status field of the PIO Setup FIS for a data transfer to the

first sector, while it sets 1 in the I bit for a data transfer to any sector other

than the first sector. Then, it sends this FIS to the host. In the E_Status field,

the device sets 1 in the BSY bit and 0 in the DRQ bit.
