Abstract
An information processor operating with a battery writes data which exists in a register of a CPU at that time into a predetermined stack area for transfer of an RAM when a suspend command is received in the normal operation state of the processor and shifts to the suspended state that the power supply to the minimum circuit components including the RAM is maintained and the power supply to the other circuit components is stopped. When insufficient power of the battery is detected in the suspended state, the information processor is started temporarily so as to automatically transfer and store the data in the RAM into a storage device using a non-volatile memory device.
