MSC1210 Reset Circuit

According to the MSC1210 datasheet, you will perform an external reset by taking RST pin high for two tOSC periods as this stops device operation, crystal oscillation, causes all digitall pins to be pulled high from that point and then followed by taking the RST pin low that initiates the reset procedure.

Herein a typical reset circuit of the MSC1210-a precision Analog-to-Digital Converter (ADC) with 8051 Microcontroller and Flash Memory schematic that can be done from the following sources: power-on reset, external reset, software reset, watchdog timer reset, and brownout reset. The figure (click to enlarge) shows a recommended external reset circuit for the MSC1210 with the serial 10kOhm resistor recomendation for any configuration of this reset type.
