[Others] How do I use a magnetic encoder, and should I use PWM or digitalread to read the angle of the motor at high rpms(2000-3000rpm)?

If say I use AS5048A magnetic encoder, to be able to find the angle at such high rpm, would it still be possible to use PWM? Or do I have to use the digital read? In that case, how would I program it?
