Claim of US Patent No. 9,740,276

1. An electronic device, comprising:
n (n is an integer greater than or equal to 2) physical layer control units which communicate with an other apparatus connected

with a standby instruction for the device itself,

wherein one physical layer control unit of the n physical layer control units generates a clock using a connected resonator,
and another physical layer control unit receives the clock generated by the physical layer control unit to which the resonator
is connected, and

wherein the n physical layer control units are connected in series in a daisy chain connection through a signal line of the
clock, and a physical layer control unit of a last stage connected in the daisy chain connection and the logical layer control
unit are connected through the signal line of the clock.
