    • An information processing device includes: a nonvolatile memory having a program area storing a program for booting a system, and backup areas each storing a backup program identical in content to the program; a process executing unit that executes the program to perform a boot process of the system; an error detection unit that performs error detection on the program in parallel with the boot process; and a reboot unit that, when the error detection unit detects an error in the program, performs a recovery process to replace the program with one of the backup programs, and reboots the system using the replaced program. In the recovery process, the reboot unit refers to history information indicating a history of replacement of the program with the backup programs, selects the backup program used for the replacement from among the backup programs, and replaces the program with the selected backup program.

    • A slave device (20), which is a communication device, receives and analyzes commands, and returns the results to a master device (10). During the command analysis period, an IIC control unit (205) and a CPU (210), which form a control unit, control an SCL control unit (201) so as to stop an SCL signal. When the value of a timer (206) is equal to or less than a threshold value, transmit data are saved in a transmission FIFO (203), control for stopping the SCL signal is canceled, and in synchronization with the SCL signal, an SDA control unit (202) transmits the data saved in the transmission FIFO (203) to the master device (10). When the value of the timer (206) exceeds the threshold value, control for stopping the SCL signal is canceled, the clock control unit is placed in a state to receive the clock signal, and the SDA control unit (202) is placed in a state to receive a slave address indicating a communication device that operates in the slave mode.
    • 作为通信装置的从设备(20)接收并分析命令,并将结果返回给主设备(10)。 在命令分析期间,形成控制单元的IIC控制单元(205)和CPU(210)控制SCL控制单元(201)以停止SCL信号。 当定时器(206)的值等于或小于阈值时,发送数据被保存在发送FIFO(203)中,用于停止SCL信号的控制被取消,并且与SCL信号同步,SDA 控制单元(202)将保存在传输FIFO(203)中的数据发送到主设备(10)。 当定时器(206)的值超过阈值时,停止SCL信号的控制被取消,时钟控制单元处于接收时钟信号的状态,并且SDA控制单元(202)被置于 状态以接收指示在从模式下操作的通信设备的从地址。
