Claim Text:
1. An oscillation circuit that generates an oscillation signal by oscillating an oscillation element, the oscillation circuit comprising: a communication unit that receives frequency setting data for setting a frequency of the oscillation signal and frequency change data that provides 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, wherein: an address of the register storing the frequency change data is directly next to an address of the register storing the frequency setting data such that the address of the register storing the frequency change data is immediately after the address of the register storing the frequency setting data, the frequency setting data includes an integer division data and a fractional division data, and the integer division data of the frequency setting data is stored in address N and the fractional division data is stored in address N+1, where N is an integer.
