いという事態が起きる。Conventionally, when processing with two microcomputers, a reset circuit is installed in each microcomputer so that UVJ is not generated until the power supply voltage is stabilized. However, if a reset circuit is provided for each, the reset time is different, and the start time of the microcomputer 331 of the transmission section and the process section is different. In order to transfer the cheek correction data transmitted between the transmission section and the control unit 1T to the process section, if one of the microcontrollers operates and the other microcontroller is in the initial state, the processing timing will be changed. Even if there is a misalignment and one side is forwarding/crashing, a situation may occur where the other side is not receiving.
このようなタイミングのずれにより動作初期に無駄な時
間を消費し、動作速度の鈍いシステムとなる。Such a timing shift wastes time in the initial stage of operation, resulting in a system that operates slowly.
