Register 8: QEI Velocity (QEISPEED), offset 0x01C
This register contains the most recently measured velocity of the quadrature encoder. This value
corresponds to the number of velocity pulses counted in the previous velocity timer period. This
register does not update when the VELEN bit in the QEICTL register is clear.
