AS5134 Status Indicators

C2 Status Bit

This bit represents the hardware connection of the C2 configuration pin (#15) to determine, which hardware

configuration is selected for the AS5134 in question.

- C2 = low: Pin C2 is low, indicating that the AS5134 is in 3-wire mode

- C2 = high: Pin C2 is high, indicating that the AS5134 is in 2-wire

Lock Status Bit

The Lock signal indicates, whether the angle information is valid (ADC locked, Lock = high) or invalid (ADC unlocked,

Lock = low). To determine a valid angular signal at best performance, the following indicators should be set:

Lock = 1

AGC = >00H and < 2FH

Note: The angle signal may also be valid (Lock = 1), when the AGC is out of range (00H or 2FH), but the accuracy of

the AS5134 may be reduced due to the out of range condition of the magnetic field strength.
