Abstract
A low pin count (LPC) bus serial interrupt system includes: an interrupt direction signal generator configured to determine a current interrupt direction signal according to whether a host currently sends a first interrupt signal to an external device; and a level-shifter configured to convert a voltage level of a signal exchanged between the host and the external device according to the current interrupt direction signal.
