    摘要: The invention reduces unnecessary electromagnetic radiation noise associated with a step pulse of an output signal. A random number control register is a register for controlling start, standby, stop, timing or the like of output of random number data from a random number generation circuit. Random number data outputted by the random number generation circuit is stored in a rise/fall time variable data register. The data stored in the rise/fall time variable data register is replaced by random number data sequentially generated by the random number generation circuit. An output circuit is a circuit for outputting a signal from an internal circuit of a microcomputer to an external device, and the rise/fall times of the output signal from the output circuit are variably controlled in response to the random number data stored in the rise/fall time variable data register.

    摘要: This invention makes it possible to reduce a power consumption of an electronic circuit (microcomputer, for example) while preventing malfunctioning of an oscillator by appropriately setting a power supply impedance of a low frequency oscillator corresponding to an operation mode. A high frequency oscillator, a medium frequency oscillator and a low frequency oscillator are provided as sources of system clocks. In addition, there is provided a quartz oscillator to generate a clock for a timepiece. When the high frequency oscillator is in operation, a power supply impedance of the quartz oscillator is reduced to improve a noise tolerance. In a waiting period during which the high frequency oscillator, the medium frequency oscillator and the low frequency oscillator are halted, on the other hand, the power supply impedance of the quartz oscillator is increased to suppress the power consumption.

    摘要: A power consumption of a light-receiving device is reduced while a power consumption of a microcomputer that controls the light-receiving device is reduced as well. The microcomputer is structured to include a drive circuit, a sampling/detection circuit, a timer, a system clock generation circuit, a CPU, a ROM and a RAM. The CPU stops providing the light-receiving device with a power supply by turning off a P channel type MOS transistor with the drive circuit and sets the microcomputer in a standby state for a predetermined period of time. When the microcomputer is released from the standby state, the CPU starts providing the light receiving device with the power supply by turning the P channel type MOS transistor on with the drive circuit.

    摘要: The invention reduces unnecessary electromagnetic radiation noise due to an operation clock signal generated by an oscillator circuit. Random number data outputted by a random number generation circuit is stored in a frequency variable data register. The data stored in the frequency variable data register is replaced by random number data sequentially generated by the random number generation circuit. An oscillator circuit is a circuit generating a clock signal, and the clock signal is supplied as an operation clock signal to an internal circuit through an operation clock signal generation circuit. The frequency of the clock signal from the oscillator circuit is variably controlled in response to the random number data stored in the frequency variable data register. A frequency variable range control register which stores control data for controlling the range of the frequency variably controlled in response to the random number data stored in the frequency variable data register is further provided.
