Overview
The DCU3 also features a Parallel Data Interface (PDI) to receive external digital video or graphic content into the DCU3. The
PDI input is directly injected into the DCU3 background plane FIFO. When the PDI is activated, all the DCU3 synchronization
is extracted from the external video stream to guarantee the synchronization of the two video sources.
The PDI can be used to:
The PDI features the following:
1.3.14
The DCULite is a display controller designed to enable the MPC5645S to drive a second TFT LCD display up to XGA
resolution using direct blit graphics and video. The DCULite includes all features of the DCU3, including the PDI with the
following exceptions:
1.3.15
The TCON enables direct drive of the row and column drivers of display panels enabling emulation of TCON ICs used in
display panels.
