Abstract
A circuit device includes first and second physical layer circuits, a bus switch circuit that switches connection between a first bus and a second bus that comply with a USB standard, on in a first period and off in a second period, and a processing circuit that performs, in the second period, processing for transferring packets on a transfer route that includes the first bus, the first and second physical layer circuits, and the second bus. When a host chirp K/J is detected on the first bus by the first physical layer circuit, the second physical layer circuit outputs a host chirp K/J to the second bus in the state where connection between the first bus and the second bus is switched off by the bus switch circuit.
