The mailbox submodule includes support for four users and, therefore, provides four interrupt outputs. MAILBOX_Interrupt0 is mapped to the EVE INTC and MAILBOX_Interrupt[3:1] are mapped to three external host processors.
Six submailboxes are provided, allowing bidirectional communication between the ARP32 and the three external hosts:
In the case of EVE-to-EVE communication, a send-remote-receive-local scheme is used, and thus software can leave MESSAGE[5:3] unused.
The listed allocation in this section is just an example. For more information about the Mailbox module, see Mailbox.
