An information processing deviceconfigured to transmit a file stored in a memory mediumto a terminal. The information processing device includes: a specifying information creating unitconfigured to create specifying information for specifying files stored in the memory medium, by using a file name and information about the memory medium; a transmitting unitconfigured to transmit the specifying information to the terminal; and a file transmitting unitconfigured to transmit to the terminal one of the files specified by the terminal in accordance with the specifying information.

A microcomputer includes: a CPU executing a predetermined calculation process; and a PWM timer generating a PWM pulse. The PWM timer includes a RAM for storing a duty value of the PWM pulse and a PWM controller for generating the PWM pulse. The PWM controller includes a PWM counter for counting up from a predetermined value as an initial value. The PWM pulse has an unit waveform, which is generated based on comparison between the duty value of the RAM and an output value of the PWM counter. The RAM outputs a new duty value at every comparison without functioning the CPU so that the duty value of the PWM pulse is changed in chronological order.

An AD converter includes an input circuit, an operation circuit and a bus interface. The input circuit is provided with a pull-down circuit, which is capable of pulling down an analog signal input side of a sample-hold circuit whether an analog signal is inputted or not. The operation circuit is provided with a reference voltage conversion result storing register, which is capable of storing a conversion result of an analog reference voltage inputted periodically separately from a conversion result of the analog signal inputted through the sample-hold circuit. The operation circuit is further provided with a check register, which is capable of writing in and reading out data for checking operation of a signal transfer system including a bus interface through the bus interface. Thus, it is made possible to confirm normality of an external part and an internal part of the AD converter.
