9.4.3 Reset

The ADC is reset in three ways: automatic at power-on, manually via the RESET pin, or manually by the RESET command.

At reset, the serial interface, conversion-control logic, digital filter, and register map values are reset. The RESET bit of the STATUS0 register is set after a reset occurs. Clear the bit to detect the next device reset. If the START pin is high after reset, the ADC immediately begins conversions after reset.
