Abstract: reliability and decreases the overall cost of the system. Power on reset control ensures that the start-up , during a power fail or brown out condition. This signal stops system operation to prevent unintended operation. In addition, this signal also blocks any read or write operations to minimize EEPROM corruption. , Non-volatile I/Os save system state when power fails. In addition, it allows continuous control of external circuitry, such as ASICs. These outputs can serve as DIP switch replacements or can "pre-configure" the ... Original
