Obsolesced Commands
Certain obsolesced commands are supported. Commands Read Long and Write Long are to be treated differently
(see “Read/Write Long” section immediately following).
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 SiI3114, as the ATA interface 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.
In this command, the Data FIS must use the format described in Table 33.
