Introduction
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 1-22 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 con-
figuration does require external address multiplexers, but the QUICC controls the multiplex-
ers. 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.
