Feature code. This register is mainly
reserved for internal use but does have two
bits that may be useful to some users:
If bit 1 (value 0x0002) is set, the control loop
is 2 ms, otherwise the control loop is 1 ms.
If bit 0 (value 0x0001) is set, a sensor DI/O is
present, otherwise there is no sensor DI/O.
Reserved Registers:
Reading these values will return zero, and writes are ignored.

Spline Download Area:
These registers are write only. Reading them will return zero. This area is used to download
intervals and points in a spline. This is a much more efficient alternative to using individual New
Spline Point and Set Spline Interval/End Segment commands. For details on using this Spline
Download Area, see Downloading Splines to the RMC.
