used in a variety of applications. The flexibility has been
significantly improved, over that of the older MC33991 and
MC33970 devices, with the addition of the Velocity Ramp
configuration features that are available in the RMPSEL
indicators) require smooth, low speed movement. For these
applications, the damping of the pointer can be optimized
with the HC and HCP bits of the RMPSELR.

characteristics that are possible with the device. Once
configured, the damping can be dynamically enabled and
disabled using the HE bits of the Position registers.
