Further, the content of the device state to be recorded may be, for example, a record relating to what instruction command is received by the CPU 104 in accordance with the application software. Further, the content of the device state to be recorded may be, for example, a record regarding what the application software is accessing in the I / F circuit 109 via the control circuit 103.
なお、制御回路１０３は、上記機器状態の情報について、予め指定した回数（ｎ回：ｎ＝１、２、・・・５回程度）分の情報を、記録回路１０７に記録する。この場合、制御回路１０３は、例えば、ＦＩＦＯ（Ｆｉｒｓｔ Ｉｎ Ｆｉｒｓｔ Ｏｕｔ）方式で、係る情報を常時上書きして記録してもよい。ＦＩＦＯ方式は、一般的な手法であるため、詳細な説明は省略する。
In addition, the control circuit 103 records information for the number of times designated in advance (n times: n = 1, 2,..., About 5 times) in the recording circuit 107 with respect to the device state information. In this case, the control circuit 103 may always overwrite and record the information by, for example, a FIFO (First In First Out) method. Since the FIFO method is a general method, detailed description is omitted.
この場合、記録回路１０７には、指定回数分の最新情報が保持される。
In this case, the recording circuit 107 holds the latest information for the specified number of times.
なお、上述した記録部に記録する情報は、例として示したものであり、情報の種類を限定するものではない。
