Abstract
Apparatus and method are described, illustratively in an LVLS master/slave system, for detecting a circuit failure, shutting down the system as if a normal power down function has occurred, but restarting the system. Signals, including power and ground lines are monitors, mal-functions detected and the apparatus put into a power down sequence. Illustratively in the LVLS system, driving a signal line to either the power or ground rails is used as a signal to the apparatus to enter the power down sequence. The present invention, after a programmable time, then drives the signal line to the opposite rail thereby signaling the system to restart—a wake up mode. After a programmable time, the signal line is released and the system resumes normal operation.
