AS5600 − Detailed 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 default range is a full 0 to 360

degrees, but when a narrow range is configured, the full

resolution of the output is automatically scaled to the

configured angular range. The angular range must be greater

than 18 degrees. To configure the angular range, see “Angle

Programming” on page 21.

CONF Register

The CONF register supports customizing the AS5600. Figure 22

shows the mapping of the CONF register.

ANGLE/RAW ANGLE Register

The RAW ANGLE register contains the unscaled and unmodified

angle. The scaled and filtered output value is available in the

ANGLE register.
