Summary:PROBLEM TO BE SOLVED: To provide a debug control circuit capable of improving the utilization efficiency of a memory without leaving undesired signals in a memory in debugging operation.SOLUTION: The debug control circuit for acquiring signals for debugging, which includes: a memory that stores signals used for observation; a signal selection section that selects a signal used for determining whether or not a cancellation should be made; a trigger detection section that detects a trigger for canceling from signals selected by the signal selection section; and a memory control unit that controls to discard the stored signal which is used for observation from the memory using the trigger detected by the trigger detection section.SELECTED DRAWING: Figure 1 【課題】 デバッグにおいて、不要な信号をメモリに残すことなく、メモリの利用効率を上げる。【解決手段】 デバッグのための信号を取得するデバッグ制御回路において、 観測に使用する信号を記憶するメモリと、キャンセルするかどうかを判断するために用いる信号を選択する信号選択部と、信号選択部で選択された信号からキャンセルするためのトリガを検出するトリガ検出部と、トリガ検出部から検出されたトリガでメモリから記憶した観測に使用する信号を破棄するよう制御するメモリ制御部とを有している。【選択図】 図1
