1.7 Control/Status Registers
www.DataSheet4U.com The control and status registers in the SpaceWire router provide the means to control the opera-
tion of the router, set the router configuration and parameters or monitor the status of the device.
The registers are accessed using RMAP command packets received by the configuration port.

5. Typical Applications
www.DataSheet4U.com
The AT7910E SpaceWire router is perfectly suited for development of applications requiring a
standalone router, a terminal node with SpaceWire interface or a mixed configuration of the two
previous ones.
5.1 Stand-alone router
The AT7910E SpaceWire Router may be used as a stand-alone router with up to eight
SpaceWire links connected to it. Configuration of the routing tables etc. may be done by sending
SpaceWire packets containing configuration commands to the router.

5.2 Node interface
The SpaceWire Router has two external ports which enable the device to be used as a node
interface. The equipment to be connected to the SpaceWire network is attached to one or both
external ports. One or more SpaceWire ports are used to provide the connection into the
SpaceWire network. Unused SpaceWire ports may be disabled and their outputs tri-stated to
save power. In this arrangement configuration of the routing tables and other parameters may
be done by sending configuration packets from the local host via an external port or from a
remote network manager via a SpaceWire port.
