0012 description:
0013 The Yamaha YAS530 magnetometers is a line of 3-axis magnetometers
0014 first introduced by Yamaha in 2009 with the YAS530. They are successors
0015 of Yamaha's first magnetometer YAS529. Over the years this magnetometer
0016 has been miniaturized and appeared in a number of different variants.

0038 description: The YAS530 sensor has a RSTN pin used to reset
0039 the logic inside the sensor. This GPIO line should connect
0040 to that pin and be marked as GPIO_ACTIVE_LOW.

0045 The polarity, whether the interrupt is active on the rising
0046 or the falling edge, is software-configurable in the hardware.
