External Memory Map

External Memory Map
The RSP memory and control registers map into the host CPU address space
as defined in the file rcp.h.
This memory map is used by the CPU program to manage the RSP.
It is also convenient to use this address map with the RSP assembler
(rspasm) and RSP simulator (rsp). Since only the lower 12-bits of addresses
and branch targets are used, the upper bits are safely ignored.
Chapter 4, "RSP Coprocessor 0", details this address space; in particular,
Table 4-6, "RSP Coprocessor 0 Registers (CPU VIEW)," on page 94 and
Table 4-7, "Other RSP Addresses (CPU VIEW)," on page 95.
General-purpose SU and VU registers cannot be addressed externally.
