Abstract
Some microprocessors and microcontrollers have a bi-directional reset pin. In such devices, output signals on the reset pin are decoded by reset reason decode logic circuitry. The output of the reset reason decode logic can be provided to another device or processor, which generates a readily recognizable output signal indicative of a reason why the processor reset. Output signals that can indicate why a processor was reset can include a high or low state of different durations, serial bit streams or a number of pulses, each of which correspond to and therefore identify a reason why the processor was reset.
