5.50 Mailbox to Queue Mapping Registers (RXU_MAP_Ln and RXU_MAP_Hn)
SRIO Registers
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 .
