KMZ80 comprises a cyclic redundancy check (crc) and an error detection code (edc) to ensure a fail-safe operation. if either the supply voltage or the ground line of the mixed signal ic is interrupted, a power-loss detection circuit pulls the output to the remaining connection. after conversion into the digital domain by an adc, further processing is done within an on-chip state machine. this state machine controls offset cancelation, calculation of the mechanical angle using the cordic algorithm, as well as zero angle and angular range adjustment. the internal digital-to-analog converter (dac) and the analog output stage are used for conversion of the angle information into an analog output voltage, which is ratiometric to the supply voltage. alternatively, the output signal can be transmitted digitally in a sent frame compliant to sae j2716. the configuration parameters are stored in a user-programmable non-volatile memory. the owi (accessible using pin out/data) is used for accessing the memory. in order to protect the memory content a lock bit can be set. after locking the non-volatile memory, its content cannot be changed anymore. 6.1 angular measurement directions the signals of the mr sensor bridges depend only on the direction of the external magnetic field vector h ext , which is applied parallel to the plane of the sensor. in order to obtain a correct output signal, exceed the minimum saturation field strength. aaa-029336 h e x t figure 2.?angular measurement directions since the anisotropic mr (amr) effect is periodic over 180, the sensor output is also 180-periodic. the angle is calculated relative to a freely programmable zero angle. the dashed line indicates the mechanical zero degree position. 7 analog output KMZ80 provides an analog output signal on pin out/data (if bit 12 in register sys_setting is set to logic 0; see table 49 ). the measured angle is converted linearly into a value, which is ratiometric to the supply voltage v dd . either a positive or a negative slope is provided for this purpose. table 3 describes the analog output behavior for a positive slope. a magnetic field angle, above the programmed maximum angle max , but below the clamp switch angle sw(cl)
