Abstract
In general, this disclosure describes techniques for implementing a system-wide reset of multiple devices. The techniques ensure that when any one of the devices of the system is reset, all the devices are reset. For example, a system includes a master reset device and a plurality of slave reset devices that are interconnected by a single reset line to provide improved robustness against electrostatic discharge (ESD) and electromagnetic pulse events. The master reset device detects a reset signal on the reset line and retransmits a true reset signal on the reset line in response to detecting the reset signal. Additionally, the master reset device may enter a blocking state after retransmitting the true reset signal to prevent detecting the reset signal that it transmitted on the reset line to avoid reset lockup.
