Reset Timing Specifications
Table 9 lists specifications for the reset timing parameters shown in Figure 10
Figure 10 shows reset timing for the values in Table 9.

8FlexBus
A multi-function external bus interface called FlexBus is provided on the MCF5482 with basic functionality to interface to
slave-only devices up to a maximum bus frequency of 66 MHz. It can be directly connected to asynchronous or synchronous
devices such as external boot ROMs, flash memories, gate-array logic, or other simple target (slave) devices with little or no
additional circuitry. For asynchronous devices, a simple chip-select based interface can be used. The FlexBus interface has six
general purpose chip-selects (FBCS[5:0]). Chip-select FBCS0 can be dedicated to boot ROM access and can be programmed
to be byte (8 bits), word (16 bits), or longword (32 bits) wide. Control signal timing is compatible with common ROM / flash
memories.
