1.1 MCF548x Family Overview  
The MCF548x family is based on the ColdFire V4e core, a complex which comprises the  
ColdFire V4 central processor unit (CPU), an enhanced multiply-accumulate unit (EMAC), a  
memory management unit (MMU), a double-precision floating point unit (FPU) conforming  
to standard IEEE-754, and controllers for caches and local data memories. The MCF548x  
family is capable of performing at an operating frequency of up to 200 MHz or 308 MIPS  
(Dhrystone 2.1).
