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.

RSTI and FlexBus data lines are synchronized internally. Setup and hold
times must be met only if recognition on a particular clock is required.
