Operation cases

The most complete and accurate solution for a MCU to read the angle of a magnet is the SPI
interface.
4.1 One Device SPI mode, unidirectional – 3 wire
The AS5048-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.
