Power supplies for microprocessor systems are often complicated by the need to take care of the special requirements of non-volatile read/write memory. Where battery backup CMOS RAMs are used, for example, it is important to ensure that the RAMs are disabled when the primary supply is removed.And when shadow-type NV memory is included the backup transfer must be initiated and
