AS5600 − Register Description
ZPOS/MPOS/MANG Registers
These registers are used to configure the start position (ZPOS)
and a stop position (MPOS) or maximum angle (MANG) for a
narrower angular range. The angular range must be greater
than 18 degrees. In case of narrowed angular range, the
resolution is not scaled to narrowed range (e.g. 0° to
360°(full-turn) → 4096dec; 0° to180°→2048dec). To configure
the angular range, see Angle Programming.
CONF Register
The CONF register supports customizing the AS5600. Figure 22
shows the mapping of the CONF register.

Note(s):
1. Forced in Low Power Mode (LPM)
ANGLE/RAW ANGLE Register
The RAW ANGLE register contains the unscaled and unmodified
angle. The scaled output value is available in the ANGLE register.
Note(s): The ANGLE register has a 10-LSB hysteresis at the limit
of the 360 degree range to avoid discontinuity points or
toggling of the output within one rotation.
