Abstract
PURPOSE: To display a data to a hexadecimal light emitting diode, by freely switching a program address and the data under the control of a program without manual operation.
CONSTITUTION: In the case of an address display, the terminals Q and Q' turn on a light emitting diode display circuit 18 in response to the output of a selection signal line 106 in the initial state of the flip-flops 12 and 13 respectively As a result, an address driver 11 becomes active and an address bus 101 is connected to a bus 107. In the case of a data bus display, a bit of a data bus 100 is connected to a terminal D of a bus driver control circuit 13. Then a data is delivered to the bus 100 synchronously with the output of a data latch strobe signal line 104. Thus the data is displayed at the display circuit 18.
