In wake on change mode, the TMAG3001 monitors either one of the magnetic axes or the angle output for a change and wakes up the system by providing an interrupt response. When user interfaces such as scroll wheels are used to wake up the system, this feature is incredibly advantageous. This device can be configured to provide a wake on change response in standby, active or the wake and sleep mode, where when an interrupt response is obtained, the new sensor measurement is used as the reference threshold for the successive measurements. Figure 2-6 shows the device response where the device is responsive to the X magnetic field and Figure 2-7 shows the device response where the device is responsive to the angle measurements.
