6.4.1 Standby (Trigger) Mode

The TMAG5273 goes to standby mode after first time powering up. At this mode the digital circuitry and oscillators are on, and the device is ready to accept commands from the primary device. Based off the commands the device can start a sensor data conversion, go to power saving mode, or start data transfer through I2C interface. A new conversion can be triggered through I2C command or through INT pin. In this mode the device retains the immediate past conversion result data in the corresponding result registers. The time for the device to go from power up to standby mode is listed as Tstart_power_up in the Power up & Conversion Time table.
