Abstract
PURPOSE: To establish the input unit easy for the confirmation of capacity of IC memory, by testing the memory and displaying the final address in response to the memory capacity.
CONSTITUTION: The input data in response to the operation of data key 1 is stored in the IC memory 3 via the processor 2 and displayed in the display section 6 via the selector 4 and register 5. When this input unit is at memory test mode with the operation of the function key 7, the address counter 9 is advanced with the test signal from the memory test circuit 8, the test data from the circuit 8 is stored in the address location of the memory 3 indicated with the counter 9 and the test data is displayed in 6 via the circuit 8, selector 4 and register. When this test is finished, the advancement of the counter 9 is stopped, and the final address from the counter 9 corresponding to the capacity of the memory 3 is similarly displayed to the unit 6 to establish the input unit easy for the confirmation of memory capacity of IC memory.
