Power Supply Connection:
- Connect the power supply pins (VDD and GND) to a stable voltage source within the specified range (3.0 V - 5.25 V).
SPI Configuration:
- Configure the SPI interface according to the datasheet specifications.
- Ensure proper clock polarity (CPOL) and phase (CPHA) settings for communication.
Initialization:
- After powering up, initialize the device by sending the appropriate commands via SPI to configure the operating parameters as needed.
Reading Angle Data:
- Use the SPI interface to read angle data from the sensor registers.
- The angle data is provided in a 14-bit format.
Entering Sleep Mode:
- To reduce power consumption, enter sleep mode by writing to the appropriate register.
- In sleep mode, the device consumes approximately 1 μA.
Waking Up from Sleep Mode:
- Wake up the device by applying a rising edge on the CS pin or by sending a wake-up command via SPI.
Handling Magnetic Field:
- Ensure that the magnetic field strength is within the operational range (20 mT - 80 mT) for accurate readings.
Error Handling:
- Monitor error flags and status bits to ensure reliable operation and take corrective actions if necessary.
