Summary:Methods and systems for handling a single event upset. The methods include, and/or the systems include functionality for, receiving, from a monitored device, data at a first input of an initial state change device; detecting, based on receiving the data, a state change; asserting, based on detecting the state change, an initial state change device enable signal; transferring the first data from the first input to a first output of the initial state change device (which may be operatively connected to a second input of a state hold device); triggering, based on detecting the state change, a delay counter; making a determination that the delay period counted by the delay counter expired without receipt of an error detection signal; and based on the determination, asserting a state hold device enable signal to allow the data to pass from the second input to a second output of the state hold device.
