Description
Microcontroller and microprocessor based systems rely on processor supervisory functions to insure stable operation. The most basic of all these functions is managing the processor reset input. To ensure stable operation, the processor must be held in reset any time supply voltage is out-of-tolerance. Once supply voltage is in-tolerance, the processor must be maintained in reset for an additional time period to ensure a stable start-up. The processor reset function may be contained on-board the processor itself, or may be externally implemented using discrete components or a supervisor IC.
