8.1.4 Magnetic Limit Check

The TMAG5173-Q1 enables magnetic limit checks for single or multiple axes at the same time. Figure 8-4 to Figure 8-7 show examples of magnetic limit cross detection events while the field going above, below, exiting a magnetic band, and entering a magnetic band. The device will keep generating interrupt with each new conversion if the magnetic fields remain in the shaded regions in the figures. The MAG_THR_DIR and THR_HYST register bits help select different limit cross modes.
