Abstract
An oscillation circuit, an oscillator, an electronic device, and a moving object which are capable of adjusting an output frequency in a high modulation bandwidth with a high level of accuracy and adjusting a timing at which the output frequency is changed are provided. The oscillation circuit generates an oscillation signal by oscillating an oscillation element and includes a communication unit that receives frequency setting data for setting a frequency of the oscillation signal and frequency change data which is given a timing at which the frequency of the oscillation signal is changed on the basis of the frequency setting data, by serial transfer, and registers in which the frequency setting data and the frequency change data received by the communication unit are stored, respectively. An address of the register storing the frequency setting data is continuous with an address of the register storing the frequency change data.
