Note that in order for the selected curve to be active, bit 4 of CV 29 must also
be set to 1. If CV 29, bit 4 is 0, the throttle response will be linear (straight
line).
The speed curves can be used in 14, 28 and 128 speed step modes.
Bit 7 is defined by the NMRA RPs as the Mid Range Speed Step select bit.
The DSD does not implement this feature and will ignore commands that
attempt to program this bit with a 1 (i.e., data values between 128-255).
Default value: 0
