Obsolesced Commands
Certain obsolesced commands are supported as shown in the table above. Commands Read Long and Write Long are to
be treated differently (see the following section)
Read/Write Long
Read Long and Write Long commands are implemented in accordance with the ATA/ATAPI-3. The PIO Mode used
(Mode 0) is of no significance in the SiI3512 controller, as the data path interface between the PCI and the
Link/Transport logic is internal. The number of vendor-specific bytes is provided by the Serial ATA PIO Setup FIS from
the downstream device as follows:
n = ((XC – 512) + 1) 2
(i.e., XC – 512 divided by 2 with round up)
where:
n is the number of vendor-specific bytes.
XC is the transfer count.
The total number of data dwords in the Data FIS is given by:
m = (XC + 3)
4
(i.e., XC divided by 4 with round up)
where:
m is the number of data dwords in the Data FIS, excluding the FIS header (and CRC).
XC is the transfer count.
