Abstract

PURPOSE:To perform the high-speed transmission processing of signals by increasing the response speed of a transmitter by making an interruption by a priority control circuit on detecting the input of an input circuit for a signal requiring fast processing and then by performing transmission requiring fast processing by intermitting normal transmission. CONSTITUTION:When a signal with priority BITD2 changes from ''0'' to ''1'' during the transmission of normal input D1, request IRQ for interruption is sent from parallel input element 11 to microcomputer 12 via priority control circuit 25 and computer 12 is switched to a priority transmission program to enter into interruption processing. Then, contents F1 and F2 of priority BIT D2 are transmitted following priority transmission start marker signal E. Finishing said process, priority end marker signal G is transmitted and normal transmission is restarted.
