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.

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.
