7.2 Pulse Width Modulation (PWM) Output

The AS5132 provides a pulse width modulated output (PWM), whose duty cycle is proportional to the absolute angle position. Figure 15 shows

the output format. In case of an internal error the high pulse contains 12 steps. An error can be easily identified by the external microcontroller.

The zero degree angle position is build with 16 steps (12 + 4) high and 359 steps low followed by 8 exit steps.
