Operation cases

The most complete and accurate solution for a MCU to read the angle of a magnet is the SPI
interface.
One Device SPI mode, unidirectional – 3 wire
4.1
The AS5048-EK-AB can be directly connected to an industry standard SPI port of a microcontroller.
The minimum connection requirement for unidirectional communication (angle + alarm values
reading) between the microcontroller and the AS5048 are MISO, SCK, SS/.
The angle will be read at each 16-bit SPI transfer. See AS5048 datasheet register table, register
3FFFh.
