Detailed Description

VEL – Velocity register (0x3FFC, read-only)

Bits	Name	R	Description
0-13	VEL_value	R	Measured velocity (14-bit two’s complement value)
14-15	(reserved)	-	Reserved bits (reads 0)

VEL_value is a signed 14-bit integer representing the rotational velocity. The value is given in two’s complement format. A positive value indicates rotation in the default direction (DIR=0 defined direction), while a negative value indicates rotation in the opposite direction. Scale: 24.141 °/s per LSB (datasheet V_Sens). When the magnet is stationary, the velocity output has RMS noise per datasheet Figure 17 (e.g. 5.8 °/s typical for K=0); small non-zero readings at standstill are therefore expected.
