Definitions

  • PCs that perform control operations by inputting an on-Z-off signal from the outside have been equipped with functions such as detection of rising and falling edges of input signals, interrupt processing, and counters.
  • the invention according to claim 2 includes a selection circuit that outputs an output signal of a circuit selected by setting a register among the delay circuit and the storage circuit to the control unit, and the control unit includes an interrupt circuit, a counter circuit, or The output signal of the circuit selected by the register setting in the selection circuit is taken in.
  • the input signal can be passed through and input to the control unit, so the desired processing is performed on one input signal. This has the effect of improving usability. Further, since the combination of circuits can be changed by setting the register, a plurality of functions can be realized with one input unit, and there is an effect that the circuit is not wasted.

Abstract

Chaque terminal d'entrée (1) est connecté à une section d'entrée (2), dans laquelle un premier sélecteur (22) émet des signaux d'entrée vers un circuit discriminateur (23), un circuit détecteur de montée (24) ou un circuit détecteur de descente (25) en fonction du réglage d'un registre (4). Le circuit discriminateur (23) transmet les signaux d'entrée à un compteur. Le circuit détecteur de montée (24) et le circuit détecteur de descente (25) détectent les transitions des signaux et utilisent ces transitions pour traiter une interruption. Lorsqu'une unité centrale (CPU) (3) modifie le réglage du registre (4), les signaux d'entrée connectés au terminal d'entrée (1) peuvent être commutés pour une fonction parmi plusieurs fonctions.
