HYST_SET
This register sets the Hysteresis that is placed in between the Screen Rotation states. The KX022
ships from the factory with HYST_SET set to ±15° of hysteresis. A different default hysteresis can be
requested from the factory. Note that when writing a new value to this register the current values of
RES0 and RES1 must be preserved. These values are set at the factory and must not change. Note
that to properly change the value of this register, the PC1 bit in CTRL_REG1 must first be set to “0”.
