9.4.1.2 RESET Pin

Reset the ADC by taking the RESET pin low for a minimum of tw(RSL) and then returning the pin high. After the rising edge of the RESET pin, a delay time of td(RSSTA) is required before communicating with the device; see the I2C Timing Requirements table for reset timing information.
