9.5.3 Router Control Register
The router control register address is 258 (0x0000 0102).
The router control register sets various control bits in the SpaceWire router. Router functions which
can be controlled are:
• Request an output port to initiate start-up when an input packet addresses that output port but
it is not ready to receive data.
• Disconnect a SpaceWire port when no activity is detected on the port for the timeout period
duration.
• Enable output port timeouts which request the output port to flush when a packet becomes
blocked for a timeout period.
• Enable the a router ports to address themselves i.e. provide a loop-back capability.
The router control register fields are shown in Figure 9-5 and described in Table 9-10.
