Abstract:
A data processing apparatus has a data saving control portion. At shutdown, within the period after a fall in the source voltage is detected until the source voltage falls down to the lower limit at which the apparatus is guaranteed to operate, the data saving control portion saves to a non-volatile memory all the data needed to restore the state of an electronic circuit portion.
