9.1.2 OTP Memory Assignment

9.1.3 User Selectable Settings

The AS5045B allows programming of the following user selectable options:

- PWMhalfEN_Indexwidth: Setting this bit, the PWM pulse will be divided by 2, in case of quadrature incremental mode A/B/Index setting

of Index impulse width from 1 LSB to 3LSB

- Z [11:0]: Programmable Zero / Index Position
