Abstract
A semiconductor integrated circuit includes a central processing unit, a hardware function block that outputs a plurality of hardware signals to be transmitted to an external device independently of the central processing unit, a virtual general purpose input/output (GPIO) finite state machine that transforms the plurality of hardware signals to a virtual GPIO payload, and an I3C communication block that transmits the virtual GPIO payload to the external device through a serial data line and a serial clock line.
