9.1.2 OTP Memory Assignment
Table 12. OTP Bit Assignment
9.1.3 User Selectable Settings
The AS5245 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
- MagCompEN: The green/yellow mode can be enabled by setting of this bit.
- Output Md0: Setting this bit enables sync- or 10bit incremental mode
- Output Md1: Setting this bit enables sync- or 12bit incremental mode
- Z [11:0]: Programmable Zero / Index Position
- CCW: Counter Clockwise Bit
- RA [4:0]: Redundant Address: an OTP bit location addressed by this address is always set to “1” independent of the corresponding
of Index impulse width from 1 LSB to 3LSB.
original OTP bit setting
ccw=0 – angular value increases in clockwise direction
ccw=1 – angular value increases in counterclockwise direction
