The watt-hour meter LCD driving control integrated circuit SM9913 typical application circuit is as shown. The E2PROM uses the 93C46 type 64×16b electrical erase programmable memory. The SM9913's ERROR output port can be used to test or read the data error and the internal data processing error of E2PROM, it outputs the low level voltage. It will outputs the high level voltage in following circumstances:1.Writing E2PROM data error or reading E2PROM data error; 2.Working process display data writing internal registers error; 3.Internal trigger is not working properly.
