... The reset output is typically connected to the reset input of a µP. A µP’s reset input starts or restarts the µ known state. The MAX6340/MAX6421–MAX6426 µP supervisory circuits provide the reset logic to prevent code-execution errors during power-up, power-down, and brownout conditions (see Typical Operating Characteristics) ...
