Abstract:
1. An electronic device, comprising: an output unit that outputs data; a data memory control unit that causes a data memory unit to store data specified by an input operation; a mode setting unit that sets a limited mode in which limitations are imposed on the input operation; a limited mode operating unit that controls limitation of the input operation and output of the data by the output unit based on a setting of the limited mode by the mode setting unit; a detecting unit that detects occurrence of an interruption event; a determining unit that determines whether the limited mode is set by the mode setting unit when the detecting unit detects the occurrence of the interruption event; a first control unit that controls, upon determination by the determining unit that the limited mode is not set, the limited mode operating unit so that the limited mode operating unit does not limit the input operation and so that the limited mode operating unit, in response to the interruption event detected by the detecting unit, reads out the data stored in the data memory unit and causes the output unit to output the data stored in the data memory unit; and a second control unit that controls, upon determination by the determining unit that the limited mode is set, the limited mode operating unit so that the limited mode operating unit limits the input operation and so that the limited mode operating unit, in response to the interruption event detected by the detecting unit, causes the output unit to output predetermined data instead of the data stored in the data memory unit.
