L64118 MPEG-2 Transport Controller with Embedded MIPS CPU (TR4101) 17
Table 2
PBus to EBus Address Mapping
:
Note that the PBus addresses are not driven on the EBus, but rather
are routed to the SDRAM controller. The two Mbyte and eight Mbyte
mode are software compatible with the L64108 code, since the
External Space 2 (ES2) of the L64108 is located at PBus address
0x0080.0000 (by default).
Table 3 summarizes the L64118 address space.
