3.2.2 Non-Index Mode (HI_CONTROL.ENVB=0, HI_CONTROL.AUTOINC=1)
In non-index mode, the Vertex Buffer is not used. Instead, CPU sends all of the geometry data. Just like index-
mode, the number of vertices and an index must be transferred first. In this case, a dummy value (0xFFFFFFFF)
must be used as an index.
Figure 9.6- 9 Non-Index Mode
The transferred data are decoded using HI_ATTRIB0~HI_ATTRIB9.
Note that when float or half-float format data is transferred to the Host-Interface, NaN or Infinite values
must not be transferred.
