Abstract
PURPOSE: To enable the low speed operation in synchronizing with the low speed unit, by generating the clock for one cycle's share every incoming of start signal, in operating the control unit through connecting to low speed microprogram control unit.
CONSTITUTION: FF12...15 constitute the ring counter and operate as the clock circuit. Further, when the mode switching signal is switched to "0" level, the AND circuits 16, 19 are closed, the output of FF15 is fed to FF12 via the AND gate 19, and the basic clock T is fed to FF15 via the AND gate 17. Further, the gate 19 is open only when the start signal LSTART of "1" level is given externally. Accordingly, in operating in connection with the microprogram control unit of low speed, the clock for one cycle's share in produced every incoming of start signal, allowing to perform low speed operation in synchronizing with the low speed unit.
