To enable StreamDAC set the number of points to a value greater than zero, to disable set the value to zero.
When loading multiple blocks of points, byte 6 (Number of Points) should be set to the total number of points the DAC should cycle
through.
Up to 128 points can be loaded, 16 at a time. Use bits [0:2] in byte 9 to select which block of 16 is being loaded.
5.3.23 - SetDefaults (SetToFactoryDefaults)
Executing this function causes the current or last used values (or the factory defaults) to be stored in flash as the power-up defaults.
The UE9 flash has a rated endurance of at least 20000 writes, which is plenty for reasonable operation, but if this function is called
in a high-speed loop the flash could eventually be damaged.
Note: Do not call this function while streaming.
