Applications
Figure 9-29 shows the interface to flash EPROM devices. In this design, the assumption is
made that only the MC68EC030 will access this array. The inverter is only required if DRAM
is used elsewhere in the system. This design assumes that the write operations are CE con-
trolled, rather than WE controlled. Most flash EPROM manufacturers now support this alter-
native timing method.
9-81
The QUICC CONFIG2–CONFIG0 pins are shown selecting
slave mode and a 32-bit port size for CS0. Thus, the CONFIG2–
CONFIG0 pins as shown are appropriate for the flash EPROM,
not the regular EPROM.
