Abstract
PURPOSE: To realize the zero suppression function and to execute the shift right easily, by comparing the contents W and R of the wirte-in and readout address register, and taking W=R as the uppermost digit display timing and inhibiting the display with W≤R.
CONSTITUTION: The write-in address register WAR adds 1 to the content every time new data is given, and the readout address register RAR subtracts 1 from the content every time the display timing pulse is delivered. The magnitude of the content W of the register WAR and the content R of the register RAR is compared. The uppermost digit display timing is taken when W=R, and the display timing in the next order is taken as the lowermost digit display timing, the display timing after that is taken from the display timing for each digit from the lowermost digit to the uppermost rank digit sequentially. If the result of comparison is W≤R, the display of the display unit is inhibited. Thus, zero-suppression function is inhibited with a simple constitution and shift right can easily be made.
