Register FIS with Status[BSY]=0 and Error[ABRT] = 1
prior to transmitting a CLOSE sequence.
Unrecovered D2H Reg FIS
The LSISASx12 sets this read-only bit when the STP Tar-
get receives an R_ERR in response to a second attempt
to transmit a D2H Register FIS. If this occurs, the STP
Target transmits a CLOSE sequence to close the connec-
tion.
Unrecovered PIO Setup FIS
The LSISASx12 sets this read-only bit when the STP Tar-
get receives an R_ERR in response to a second attempt
to transmit a PIO Setup FIS. If this occurs, the STP Tar-
get transmits a CLOSE sequence to close the connec-
tion.
Unsupported FIS Received
The LSISASx12 sets this read-only bit when the STP Tar-
get receives one of the following FIS Types:
If the STP Target receives one of these FIS types, the
STP Target transmits an R_ERR, followed by a CLOSE
sequence to close the connection.
Payload/Transfer-Count Mismatch
The LSISASx12 sets this read-only bit when the number
of dwords received in a Host-to-Device DATA FIS does
not match the Transfer Count that was placed in the pre-
viously sent PIO Setup FIS. If this occurs, the Application
Layer notifies the Link Layer to send an R_ERR, and a
D2H Register FIS is transmitted to the host with a SCSI
Sense Key of ILLEGAL REQUEST (0x5) placed in the
Error register.
