User Guide
A remote host can access the RapidIO registers by sending
MAINTENANCE
transactions
targeted to this local RapidIO IP core. The Maintenance module processes
MAINTENANCE
transactions. If the transaction is a read or write, the operation is
presented on the Maintenance Avalon-MM master interface. This interface must be
routed to the System Maintenance Avalon-MM slave interface. This routing can be
done with a Qsys system shown by the routing to the Concentrator's system
Maintenance Avalon-MM slave in Figure 4–10. If you do not use a Qsys system, you
can create custom logic as shown in Figure 4–11.
Maintenance Module
The Maintenance module is an optional component of the I/O Logical layer. The
Maintenance module processes
MAINTENANCE
transactions, including the following
transactions:
■ Type 8 –
MAINTENANCE
reads and writes
■ Type 8 –
Port-write
packets
