Figure 10-12 16-bit Pixel Format (4:4:4:2/TTX) for Use in Frame Buffer
Pixels in 16-bit format which are stored in TTX format contain two 5-bit colour look up
vectors and two flash mode indicator bits. The flash mode indicator bits are used to
choose the flash rate and the flash phase. The meaning of flash is: The colour alternates
between two 5-bit colour vectors (FlashC and Pixel) which are chosen within the format
definition.
• Non Flash: Flash can be disabled if both 5-bit colour vectors point to the same CLUT2
location.
• Inverted Flash: Inverted flash is supported by exchanging the ‘FlashC’ vector with the
‘Pixel’ vector.
