SRIO Registers

5.50 Mailbox to Queue Mapping Registers (RXU_MAP_Ln and RXU_MAP_Hn)

Messages addressed to any of the 64 mailbox locations can be received on any of the RapidIO ports simultaneously. Packets are handled sequentially in order of receipt. A block of 32 mappers directs the inbound messages to the appropriate RX queues. After a device reset, software must configure each of the mappers to map incoming messages with selected mailbox and letter numbers to the desired queue. For a given mapper n, a pair of mailbox to queue mapping registers fully define the configuration for that mapper: a low register (RXU_MAP_Ln) and a high register (RXU_MAP_Hn). Table 118 lists all of these register pairs and the associated RX mappers. The general form of an RXU_MAP register pair is summarized by Figure 113, Table 119, and Table 120. For additional programming information, see Section 2.3.4.1 .
