Abstract

PURPOSE: To simplify the processing after the start of operation, by determining whether the content of the operational register before power interruption is cleared or stored, depending on the stop reason whether the operation of calculator is stopped by power off operation by the operator or automatic power off.
CONSTITUTION: The data used for various operations are stored in the register of the memory section 4 connected to the ROM 7 so that the stop of data transfer from the key input section 1 to the memory section 4 can be made with the power switch SW and the automatic power off at the state control section 6. Further, the buffer register 16 connected to the operation section 3 judging the input data of the input section 1 and FF25 controlling the pulse generator 9 of the state control section 6 are provided, and the ROM address section 8 determines the data before power interruption is cleared or stored, depending whether the operation of the state control section 6 is made by power switch SW or power off, to control ROM 7.
