14 / 130 page  Overview PXD20 Microcontroller Data Sheet, Rev. 2 Preliminary—Subject to Change Without Notice Freescale Semiconductor 14 To secure the content of all critical information to be displayed, a safety mode can be activated to check the integrity of critical data along the whole system data path from the memory to the TFT pads. The DCU3 features the following: • Display color depth: up to 24 bpp • Generation of all RGB and control signals for TFT • Four-plane blending • Maximum number of Input Layers: 16 (fixed priority) • Dynamic Look-Up-Table (Color and Gamma Look-Up) • blending range: up to 256 levels • Transparency Mode • Gamma Correction • Tiled mode on all the layers • Hardware Cursor • Supports YCrCb 4:2:2 input data format • RLE decode inline supporting direct read of RLE compressed images from system memory • Critical display content integrity monitoring for Functional Safety support • Internal Direct Memory Access (DMA) module to transfer data from internal and / or external memory. 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: • Connect a video camera output directly to the PDI • Connect a secondary display driver as slave with a minimum of extra cost • Connect a device gathering various Video sources • Provide flexibility to allow the DCU to be used in slave mode (external synchronization) The PDI features the following: • Supported color modes: — 8-bit mono — 8-bit color multiplexed — RGB565 — 16-bit/18-bit RAW color • Supported synchronization modes: — embedded ITU-R BT.656-4 (RGB565 mode 2) — HSYNC, VSYNC — Data Enable • Direct interface with DCU3 background plane FIFO • Synchronization generation for the DCU3 1.4.14 Display Control Unit Lite (DCULite) The DCULite is a display controller designed to enable the PXD20 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: • Reduced from 4-plane to 2-plane blending • Reduced from 16 layers to 4 layers • Reduced CLUT size |
