1. A circuit device comprising:
- a detection circuit which outputs angular velocity information, based on a detection signal from an angular velocity sensor element; and
an output unit which outputs rotation number information of fixed-point notation that is obtained based on the angular velocity information,wherein the output unit can output an integer part of the rotation number information as an integer part of the fixed-point notation, and can output a decimal part of the rotation number information as a decimal part of the fixed-point notation,wherein the output unit includes multiple output modes, andwherein the multiple output modes include a first output mode in which the output unit outputs the integer part of the rotation number information and the decimal part of the rotation number information.

Abstract
A circuit device includes a detection circuit which outputs angular velocity information, based on a detection signal from an angular velocity sensor element; and an output unit which outputs rotation number information of fixed-point notation that is obtained based on the angular velocity information. The output unit can output an integer part of the rotation number information as an integer part of the fixed-point notation, and can output a decimal part of the rotation number information as a decimal part of the fixed-point notation.

19. A circuit device comprising:
-
a detection circuit which outputs angular velocity information, based on a detection signal from an angular velocity sensor element; and an output unit which outputs rotation number information of fixed-point notation that is obtained based on the angular velocity information, wherein the output unit can output an integer part of the rotation number information as an integer part of the fixed-point notation, and can output a decimal part of the rotation number information as a decimal part of the fixed-point notation, wherein the output unit includes multiple output modes, and wherein the multiple output modes include at least two output modes, among a first output mode in which the output unit outputs the integer part of the rotation number information and the decimal part of the rotation number information;
a second output mode in which the output unit outputs the integer part of the rotation number information, and the output unit does not output the decimal part of the rotation number information;
a third output mode in which the output unit does not output the integer part of the rotation number information, and the output unit outputs the decimal part of the rotation number information; and
a fourth output mode in which the number of bits of the decimal part of the rotation number information is reduced and is output by the output unit.
