Document Type and Number:
Japanese Patent JPS5460537
Kind Code:
A
Abstract:
PURPOSE: To omit the independent order for reset and thus to decrease the software quantity by adding a simple reset circuit to utilize the interruption non-permission order to the reset order.
CONSTITUTION: The output of interruption permissible FF14 is inverted through inverter 18 in reset circuit 17; gate 19 is opened and closed by the output of inverter 18; and interruption non-permission control signal DI is branched and supplied to gate 19. When CPU 13 carries out the interruption non-permission order, signal DI is produced. At this instant, FF14 is under the reset state, so signal DI is applied to interruption request FF12 via gate 19 in the form of reset signal R to reset FF12
