8.4.2.1 Single-Shot Mode and Power-Down

When the MODE bit in the Config register is set to 1, the ADS1018 enters a power-down state, and operates in single-shot mode. This power-down state is the default state for the ADS1018 when power is first applied. Although powered down, the device still responds to commands. The ADS1018 remains in this power-down state until a 1 is written to the single-shot (SS) bit in the Config register. When the SS bit is asserted, the device powers up, resets the SS bit to 0, and starts a single conversion. When conversion data are ready for retrieval, the device powers down again. Writing a 1 to the SS bit while a conversion is ongoing has no effect. To switch to continuous-conversion mode, write a 0 to the MODE bit in the Config register.
