Abstract

A gyro sensor includes a first register that stores angular velocity information; a second register that stores sensitivity deviation information of the angular velocity information stored in the first register; a serial communication circuit; and a control circuit that selects the first register or the second register in accordance with designation information supplied through the serial communication circuit. When the first register is selected by the control circuit, the angular velocity information stored in the first register is output through the serial communication circuit, and when the second register is selected by the control circuit, the sensitivity deviation information stored in the second register is output through the serial communication circuit.

Claims

1. A gyro sensor comprising:

a first register that stores angular velocity information;

a second register that stores sensitivity deviation information of the angular velocity information stored in the first register;

a serial communication circuit; and

a control circuit that selects the first register or the second register in accordance with designation information supplied through the serial communication circuit,

wherein when the first register is selected by the control circuit, the angular velocity information stored in the first register is output through the serial communication circuit, and when the second register is selected by the control circuit, the sensitivity deviation information stored in the second register is output through the serial communication circuit.

2. The gyro sensor according to claim 1,

wherein the sensitivity deviation information is a deviation between a predetermined sensitivity and the sensitivity of the angular velocity information.

3. A gyro sensor comprising:

a first register that stores velocity information;

a second register that stores sensitivity deviation information of the velocity information stored in the first register;

a communication circuit; and

a control circuit that selects the first register or the second register in accordance with designation information supplied through the communication circuit,

wherein when the first register is selected by the control circuit, the velocity information stored in the first register is output through the communication circuit, and when the second register is selected by the control circuit, the sensitivity deviation information stored in the second register is output through the communication circuit.

4. The gyro sensor according to claim 3,

wherein the sensitivity deviation information comprises a deviation between a predetermined sensitivity and the sensitivity of the velocity information.
