6.4.4 Continuous Measure Mode

In this mode the TMAG3001 continuously measures the sensor data per Sensor_Config & Device_Config register settings. In this mode the result registers can be accessed through the I2C lines. The time the device takes to go from standby mode to continuous measure mode is denoted by Tstart_measure.

OPERATING MODEDEVICE FUNCTIONACCESS TO USER REGISTERSRETAIN USER CONFIGURATIONCOMMENT
Continuous Measure ModeContinuously measuring x, y, z axis, or temperature dataYesYes
Standby ModeDevice is ready to accept I2C commands and start active conversionYesYes
Wake-up and Sleep ModeWakes up at a certain interval to measure the x, y, z axis, or temperature dataNoYes1, 5, 10, 15, 20, 30, 50, 100, 500, 1000, 2000, 5000, & 20000ms intervals supported.
Sleep ModeDevice retains key configuration settings, but does not retain the measurement dataNoYesSleep mode can be utilized by a Controller device to implement other power saving intervals not supported by wake-up and sleep mode.
