A control circuit switches an oscillation circuit from a second operation mode to a first operation mode. When a first predetermined signal is detected and mode switching permission information indicates that the switching from the second operation mode to the first operation mode is permitted, then the oscillation circuit switches from the second operation mode to the first operation mode. When the first predetermined signal is not detected and the mode switching permission information indicates that the switching from the second operation mode to the first operation mode is not permitted, then the oscillation circuit continues in the second operation mode.

Oscillation circuit, oscillator, and operation mode switching method of oscillation circuit

A circuit device includes an A/D conversion circuit that performs A/D conversion on a temperature detection voltage from a temperature sensor so as to output temperature detection data, and a digital signal processing circuit that performs a temperature compensation process on the basis of the temperature detection data, in which the A/D conversion circuit operates in a first mode, and switches to a second mode in a case where a predetermined condition is established.

Circuit device, oscillator, electronic apparatus, vehicle, and manufacturing method for circuit device

An oscillator IC includes a VDD terminal (first terminal), an OUT terminal (second terminal), an oscillation circuit for oscillating a resonator element, a mode switching circuit that switches between a normal mode (the first mode in which an oscillation signal output by the oscillation circuit is output from the OUT terminal) and a serial I/F mode (the second mode in which a signal than the oscillation signal is output or input from the OUT terminal) based on a voltage of the VDD terminal, and a control circuit that controls stop of the oscillation circuit in the serial I/F mode based on setting information that can be changed from outside.

Flexible substrate and electronic equipment

A data transfer control system includes: a port control section which controls ports Pand Prespectively connected with an electronic instrument PCand an electronic instrument PC; and a bus reset issue section which issues a bus reset. The port Pis set to a disabled state, and then the bus reset is issued to cause the electronic instrument PCto acquire an access right. The port Pis set to an enabled state after the bus reset has been issued and the electronic instrument PChas acquired the access right. After the electronic instrument PChas been detected to be in a suspended state, a resume packet is transferred to the electronic instrument PC. The port Pis set to a disabled state after the power for the data transfer control system has been turned on.
