Preliminary data sheet
2.3.2 Alpha Blending
2.3.3
Raster-ops are turned off if alpha blending is enabled.
The Drawing Engine supports alpha blending of source and destination data. The
destination data can be either 32-bit RGB:8888, 32-bit YUV8888, 16-bit RGB:565,
16-bit aRGB 4444, or 16-bit RGBa 4534. Source data can come either from the
memory or from the host data port. The alpha calculations are based on the source
and "surface" alpha values.
Raster-ops are disabled if alpha blending is selected.
The following combinations of source and destination data are supported.
Table 1: Source and Destination Data
The data for the source operand can reside in either the frame buffer memory or be
provided by the host processor via the MMIO bus. There are five source selection
options currently defined:

Source Data Location and Type
1. Source data is held in frame buffer memory (always full color data)
2. Source data is provided by the processor via the MMIO bus and is full color
3. Source data is provided by the processor via the MMIO bus and is a
monochrome bitmap
