•
WRITE LOG EXT
•
DEVICE CONFIGRATION SET
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.
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.
