11.1.2 6-bit Status Information
Table 15 Status Bits of Byte 2 of the SIU
11.1.3 8-bit Magnitude Information
The magnitude information is a value that is proportional to the magnetic field strength. A strong magnet (or close
distance between magnet and chip) will result in a high magnitude value and vice versa. When the automatic gain
control (AGC) is active (default state), it tries to keep the magnitude value stable at a value of 3F
11.2 Hall Sensor Front End (Type ID: 0001)
The Hall Sensor Front End allows configuration of each Hall Sensor. Each sensor can be disabled or connected to
either the SIN or COS signal bus. Additionally, each sensor can be inverted for differential measurement.
Each Hall Sensor is selected through a device address for the type identifier 0001,

Note: If the magnet is placed like shown in Figure 8 the encoder reading will be of zero.

must be 1 for valid data
must be 0; if this bit is set, the angular data is invalid
LINearity warning bit. Should be 0 for normal operation.
Will be 1 when the magnetic field is too high or too low
This bit is set temporarily when the magnetic field
increases, when the magnet is pushed towards the IC
This bit is set temporarily when the magnetic field
decreases, when the magnet is pulled away from the IC
