1. A method for handling a single event upset (SEU), the method comprising:receiving, from a monitored device, a first data at a first input of an initial state change device;
detecting, based on receiving the first data, a first state change;
asserting, based on detecting the first 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, wherein the first output is operatively connected to a second input of a state hold device;
triggering, based on detecting the first state change, a delay counter to count a delay period;
making, by a validation engine, a first determination that the delay period counted by the delay counter has expired without receipt of an error detection signal; and
based on the first determination, asserting a state hold device enable signal to allow the first data to pass from the second input to a second output of the state hold device.
