Patent ID: 7660975

Claim:
An electronic apparatus having a control unit, peripheral circuits having operations controlled by said control unit, and a rechargeable battery being configured to feed operational power to said control unit and said peripheral circuits, said electronic apparatus comprising: a continuous initialization device configured to initialize said control unit; and a abnormality detector configured to detect abnormalities in said control unit, said continuous initialization device outputting an first initialization signal to said control unit during at least one of a first and a second periods of time, said first period of time being when voltage supplied to said control unit is equal to or less than operation-assured voltage of said control unit, and is equal to or greater than start voltage to start operation of said control unit, said second period of time being when said voltage supplied to said control unit is greater than the lower limit of operation-assured voltage of said peripheral circuits and lower than said start voltage to start said operation of said control unit, said continuous initialization device outputting a second initialization signal to said control unit when an abnormality is detected at said control unit.
