Type Description
9
ru
Status ADC-Test¹⁾
Check of signal path with test vectors. All test vectors at
startup tested. Activation in operation via AS_ADCT
possible.
0_B Test vectors OK
1_B Test vectors out of limit
Reset: 0_B
7
ru
Status Magnitude Out of Limit¹⁾
Cyclic check of available magnetic field strength.
Deactivation via AS_VEC_MAG.
0_B GMR-magnitude OK
1_B GMR-magnitude out of limit
Reset: 0_B
6
ru
Status X,Y Data Out of Limit¹⁾
Cylcic check of X and Y raw values. Deactivation via
AS_VEC_XY
0_B X,Y data OK
1_B X,Y data out of limit (>23230 digits)
Reset: 0_B
5
ru
Status Overflow¹⁾
Cyclic check of DSPU overflow. Deactivation via AS_OV.
0_B No DSPU overflow occurred
1_B DSPU overflow occurred
Reset: 0_B
4
ru
Status Digital Signal Processing Unit
Check of DSPU, CORDIC and CAPCOM at startup.
Activation in operation via AS_DSPU possible.
0_B DSPU self-test OK
1_B DSPU self-test not OK, or self-test is running
Reset: 0_B
3
ru
Status Fuse CRC¹⁾
Cyclic CRC check of laser-cut-fuses. Deactivation via
AS_FUSE and disabled by activated autocalibration.
Note: Changing of fused parameters results in new CRC,
which differs from stored CRC --> Fuse CRC fail
0_B Fuse CRC OK
1_B Fuse CRC fail
Reset: 0_B
2
ru
Status Voltage Regulator¹⁾
Permanent check of internal and external supply
voltages. Deactivation via AS_VR
0_B Voltages OK
1_B V_DD overvoltage; V_DD undervoltage; V_DD-off; GND-
off; or V_OVG; V_OVA; V_OVD too high
Reset: 0_B
