1. A processing circuit for anomaly detection comprising:
a physical layer transmission unit configured to receive an operation request;
a physical layer control unit connected to the physical layer transmission unit, wherein the physical layer control unit switches from operating in a first operation state to operating in a second operation state according to the operation request;
a state detection unit connected to the physical layer control unit, wherein the state detection unit is configured to detect a current operation state of the physical layer control unit, and the state detection unit outputs a warning signal when the current operation state and the second operation state are not identical; and
a reset unit connected to the physical layer control unit and the state detection unit, wherein the reset unit transmits a reset signal to the physical layer control unit according to the warning signal to reset the physical layer control unit to an initial state.
