Abstract

PURPOSE:To obtain a pulse input converter using extremely small numbers of pieces of hardware and signal lines, by composing this converter of a CPU part having an interrupting function, two input reception parts and one OR part. CONSTITUTION:External UP pulse signal 3 and external DOWN pulse signal 4 are received by UP pulse input reception part 1 and DOWN pulse input reception part 2 respectively. Further, CPU part 8A is provided with an interruption function, and an internal signal input terminal and interruption input terminal. Furthermore, reception parts 1 and 2 are connected to the interruption signal input terminal of CPU part 8A via OR part 12, and UP pulse input reception part 1 to the internal signal input terminal of CPU part 8A.
