Buffered write enable. Generally, the enabling of buffered writes provides higher system performance but
recovery from access errors may be more difficult. For the ColdFire CPU, reporting access errors on operand
writes is always imprecise; enabling buffered writes further decouples the write instruction from the signaling
of the fault.

controller. In this mode, operand write cycles are effectively decoupled between the processor's local bus
and the external bus.
