Abstract
A voltage spike detection circuit for use in detecting clock edge transitions utilizes a voltage change detection circuit (16) and a voltage spike latching circuit (18). The voltage change detection circuit (16) provides an output pulse in response to each edge transition of a serial communication clock, including an edge caused by a noise spike on the serial communication clock. In response to receiving the output pulse of the voltage change detection circuit (16), the voltage spike latching circuit (18) provides an active system interrupt signal to a serial communication system. When the serial communication system receives the active system interrupt signal, the serial communication system momentarily activates a system reset signal and re-communicates the serial communication data.
