8.3.1.2 Internal Pattern Mode

There are two key differences between internal and external pattern mode:

•

Internal pattern mode only supports 1D patterns i.e the pattern data is same across the entire row or column

of the DMD (Figure 19, Figure 20).

•

Internal pattern mode enables user to design a simple system by eliminating need of an external processor to

generate and send patterns every frame. In internal pattern mode one row or one column patterns are pre-

loaded in the flash memory and a command is send to DLPC3470 controller to display the patterns.

Implementation details on how to create patterns, save patterns in Flash memory and load patterns from flash

memory into the DLPC3470 controller’s internal memory are described in SW Programmers Guide.

Internal pattern mode further provides two configurations to trigger the display of patterns, free running mode,

(shown in Figure 21) and trigger in mode (shown in Figure 22).
