I/O Location & Interrupt Level
Up to eight MC Ringnodes may be installed. Each Ringnode
must use a different I/O Location. It is recommended that each adapter
also uses a different Interrupt Level, although it is allowable for adapters
to share an Interrupt Level if necessary.

Arbitration Level
The Arbitration Level need only be changed if it is in
conflict with another adapter.
<Level 8>,
Level 9, Level 10, Level 11, Level 12, Level 13, Level 14, Level 5, Level
6, Level 7, Disabled
Transfer Mode
Streaming Enabled permits host bus data transfer rates
up to 40 MB/s. Streaming Disabled permits host bus data transfer rates
up to 20 MB/s.
When Fair mode is selected, the MC Ringnode enters an
inactive state when it releases the bus. This allows the system to service
any other arbitrating devices in order of priority before the Node requests
the bus again. In Unfair mode, the Node will immediately re-request the
bus after releasing it.

Burst Mode
BURST MODE:
Four burst modes are available for data transfer. The Delayed Release (Fair)
mode generally gives the best results. However, the user may care to experiment
with the other modes which may be better in some system configurations
(eg. multiple bus masters).
Delayed Release
- If the MC Ringnode is transferring data when another adapter requests
arbitration it will transfer about 14 more bytes before releasing the bus.
This mode is not suitable if your system memory is very slow or only 8-bit
wide, as a bus time-out may occur.
Immediate Release
- If the MC Ringnode is transferring data when another adapter requests
arbitration it will immediately release the bus. This has the effect of
reducing the arbitration latency for other adapters.
Limited Burst - In
this mode, the MC Ringnode will never transfer more than 18 bytes in each
burst. It also releases the bus immediately if another adapter requests
arbitration.
Cycle Steal - In this
mode, the MC Ringnode will never transfer more than 2 bytes in each burst.
It will also release the bus immediately if another adapter requests arbitration.
This limits the bus bandwidth used by the Node, allowing the system CPU
more processing time.
Fair/Unfair - When
Fair mode is selected, the MC Ring-node enters an inactive state when it
releases the bus. This allows the system to service any other arbitrating
devices in order of priority before the Node requests the bus again. In
Unfair mode, the Node will immediately re-request the bus after releasing
it.
