The QUICC has special features in slave mode to support the M68040 family. When the QUICC is used in
this way, it is said to be in MC68040 companion mode. Figure 9 shows how a QUICC in slave mode can
interface to a MC68EC040. (The MC68EC040 is a low-cost version of the MC68040 with identical integer
performance, but without the memory management unit (MMU) and the floating-point unit (FPU).) The DRAM
controller on the QUICC will control the accesses of the MC68EC040 (including the burst modes). This
configuration does require external address mutiplexers, but the QUICC controls the multiplexers. The
QUICC supports the MC68EC040 in other ways, such as interrupt handling and system protection features.
When it is in slave mode, the QUICC can also be interfaced to any MC68030-type bus master instead of the
MC68EC040.
