Abstract

A microprocessor system having two microprocessors, each of which has its own reset circuit, and a circuit being provided which detects under-voltage in the system supply voltage, each of said microprocessors having circuitry associated with it for inducing a simulated low voltage condition on the reset circuit of the other microprocessor to test said under-voltage detection circuit and to measure the resulting reset period generated.
