1.2
The MCF51EM256 series devices contain a version of the V1 ColdFire platform that is optimized for area
and low power. The CPU implements ColdFire instruction set architecture revision C (ISA_C) with added
capabilities:
An integrated multi-master crossbar switch on the ColdFire system busses provides access to system
resources by the CPU.
For more details on the V1 ColdFire core, see

registers:
1.2.2
System programmers use the supervisor programming model to implement operating system functions.
All accesses that affect the control features of ColdFire processors must be made in supervisor mode and
can be accessed only by privileged instructions. The supervisor programming model consists of the
registers available in user mode as well as the registers listed in
