7.6.2 Description of Each Control Command

Abort_SCSI (01H)

Aborts the SCSI control command in process of execution. After aborting the process,

The SABT bit of the MAININT register is set.

The status block is set.

It causes an interruption. If this command is issued in the state of not operating, it is ignored.

Assert_RST (04H)

Asserts the SCSI RST signal (XSRST) for 768 × T × 2 (about 46

µ

s), and then negates it.

This command releases all the signals it asserts, causing the busfree condition. The inside of the IC is not
initialized.
It sets the SCSIINT1 SRST bit after negating the RST signal, causing an interruption.
When the SCSI control command is being executed, it is forced to terminate. Only RST bit is set, though.
When the SCSI DMA command is being executed, the status block is set.

Busfree (05H)

Executes busfree.
The command is valid only in Target mode. If issued in Initiator mode, it is ignored.
It is invalid if issued while other SCSI-type command is in execution, causing a command error and a command
error interruption.
