Electronic device

An electronic device comprising:

• a power supply;
• a processing section which has a nonvolatile register and performs predetermined processing by inputting and outputting data to and from said nonvolatile register on the basis of power fed from said power supply;
• a functioning section to which power is fed from said power supply;
• and
• a power feed control section, which interrupts power feeding from said power supply to said processing section, while maintaining power feeding from said power supply to said functioning section in a state in which the processing state of said processing section which created said display data is stored in said nonvolatile register, and resumes power feeding from said power supply to said processing section in response to a predetermined condition.

An electronic device comprising:

• a power supply;
• a processing section which has a nonvolatile register and processes first data and second data by inputting and outputting data to and from said nonvolatile register on the basis of power fed from said power supply;
• a register for sequentially retaining said first data and said second data;
• and
• a power feed control section for creating a period of time during which power feeding from said power supply to said processing section is interrupted, while power feeding from said power supply to said register is maintained between processing of said first data and processing of said second data.
