Summary: | PURPOSE:To outputs the control signal for an AC induction motor and a general-use pulse signal by adding a circuit which reads the contents of a comparing register out in synchronism with the operation of other comparing registers and using hardware effectively. CONSTITUTION:A coincidence signal EQi is passed through an AND gate 113, etc., and connected to the reset/set input of a D latch 119, etc. Further, coincidence signals EQ0 and EQ1 are connected to a D latch 140 through an OR gate 138. The output of the D latch 140 comes to the readout signal of a comparing register 109 through an OR gate 142 which inputs a signal RDCM4 at the other input terminal. Similarly, coincidence signals EQ2 and EQ3 are inputted to a D latch 141, whose output comes to the readout signal of the comparing register 110 through an OR gate 143 inputting a signal RDCM5 at the other input terminal. A counter bus 104 which connects respective comparing registers and a counter 112 is connected even to a multiplexer 137. |
