9.1.2 OTP Memory Assignment

9.1.3 User Selectable Settings

The AS5145 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

- Output Md0: Setting this bit enables sync- or 10bit incrememantal mode (see Table 10).

- Output Md1: Setting this bit enables sync- or 12bit incrememantal mode (see Table 10).

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