The RESET command resets the digital filter and sets all configuration register values to default settings. A RESET command also puts the device into standby mode. When in standby mode, the device waits for a rising edge on the START/SYNC pin or a START command to resume conversions. After sending the RESET command, a delay time of td(RSSC) is required before sending the first serial interface command or starting a conversion. See the Timing Characteristics section for reset timing information.
Note that if the device had been using an external clock, the reset sets the device to use the internal oscillator as a default configuration.
