5.8 Shared Memory
The host writes Request Message Frames into a region of Shared
Memory (LSIFC909 local memory mapped to System Addresses). This
is the default method (PUSH model) for Request Message Frame
transport, where the host itself copies the Request Message Frame into
the LSIFC909 local memory. The total size of Shared Memory is
configured by the IOP on reset. Supported values are 32 Kbytes,
64 Kbytes, 128 Kbytes (default), 256 Kbytes, and 512 Kbytes. Shared
memory is accessible only through Mem0 space starting at address
0x80.
