Command
Operation

In this section, the sequence of events that can be expected and the parts that
the adapter and Host must play are described.

Sequence of

Events—

Enabling

Target Mode

The following sequence must occur to ensure proper operation of Target Mode:.

1.

Host allocates 32 bytes of memory for the Target Selection Data
Structure, to be used by the adapter when it is selected by an initiator.

Note
When Target Mode is
terminated, whether by a
Disable Target Mode
command or by a SCSI
bus Reset, the Target
Selection Data Structure
will be written by the
adapter, with the TME
bit of the Flags field
cleared. Additionally, if
a SCSI bus reset
occurred, an error of 27H
will be reported in the
Error field

2.

The Host issues a Target Mode Enable command to the RF3880. The
address of the Target Selection Data Structure is passed in the
command.

3.

The adapter is ready to accept selection by an initiator and will remain
so until a SCSI Reset occurs or the Host issues a Target Mode Disable
command.
