WARNING
The default timeout intervals of 60-80 µs or 1.3 ms are short. It may be necessary to increase the
timeout interval by a configuration command writing to the router control register. When initially
prototyping a SpaceWire system it is advisable to set the timeout interval to 1.3 s and then decrease it
to an appropriate value once basic system operation has been established.
9.5.4 Error active Register
The error active register address is 259 (0x0000 0103).
The error active register indicates the Error Active bit of the each of the port control/status registers.
By reading from this register a network manager can determine which ports currently have errors. This
register is also used to clear the error bits of the port control/status registers. To do this a write
command is sent to the error active register with bits set for those errors that are to be cleared.
The error active register fields are shown in
Figure 9-6 and described in Table 9-11.
