45 Peripheral Clock Generation To conserve power, many peripherals do not have a clock signal after reset. A bus error will occur when attempting to access peripherals without clocks. Software must initialize in two ways: 1. Peripheral clock gating on a mode basis. Based on ME_RUN_PCx, ME_LPx and various ME_PCTLx registers 2. Clock generation on a peripheral or peripheral set basis.

46 Peripheral Clock Generation Examples

47 Boot Assist Module (BAM) Overview The Boot Assist Module is a block of read-only memory which assists the boot process. Typically it is executed after RESET Features: Locates and detects application boot code Searches for a BOOTID value in pre-assigned locations in flash Can allow serial download of code into internal SRAM for execution Uses FlexCAN or esci for MPC563xM Uses FlexCAN or LINFlex for MPC560xB / P / S Can allow boot from external flash (if external bus is implemented) If an MMU is implemented, MMU pages are configured processor resources Censorship protection for internal flash module

48 SIU Pad Configuration Each pad has its own 16-bit Pad Configuration Register (PCR) Registers SIU_PCR0 to SIU_PCR230 Register number corresponds to GPIO number Not all pads have all bit fields BAM will alter defaults for some pads Software must configure pin assignments to be other than their common default GPIO assignment. MPC56xxB / P / S also includes registers to select which pin input is connected to which peripheral.

79 DCU The display driver used in Spectrum family MCU s s for instrument cluster is a combined direct un-buffered blit engine & display driver. Main advantages are Cost efficient Low memory requirement Optimized for GUI and advanced OSD Safety feature to enable safety related display content 79

80 Bliting concepts OBJECT memory Blit engine FRAME buffer Visible buffer Shadow buffer Display driver Classic solution Flexible and typically slow Needs typically 3x full frame buffer RAM for RGB888 that is 1147kB. Typically needs external fast RAM. CPU Scratch pad Needs min. 2 x resolution RAM for video input. Display frame rate asynchronous output composition DCU direct un-buffered blit engine OBJECT memory edma CPU FRAME buffer Fragmented frame buffer Bliter Display driver Fixed function and typically much faster Needs less frame buffer RAM. For RGB888 that is typically less than 160kB Suitable for single chip solutions with no external RAM. Blit functions optimized for GUI design. No RAM required for video input Display frame rate synchronous output composition 80

81 DCU features, (updated with rev2 enhancements) 16 Layers 4 planes Frame buffer limited by memory size (all memories, RAM, ROM INT,, EXT) Target size WVGA (Limited by memory bandwidth and pixel clock speed) s Support 16, 24, 32 bit color depth. Support 1, 2, 4, 8bpp indirect color mode Support TFT type LCD with 16, 18, 24bit wide digital RGB interface Alpha blend (per pixel and per layer in 4 planes) Chroma key (range per RGB component in 4 planes) Combined alpha blend and chroma key modes Font mode blending (transparency mode/alpha map) Highlight area mode. (luminance offset) Tile mode Digital video input Safety mode support Hardware cursor 81

82 DCU layers & planes Layer priority is fixed. Layers arbitrate for 4 planes on per pixel basis. The active layer that has the highest priority loads in the foreground plane 1, the next loads in foreground plane 2 etc. If no layer qualifies for the BG plane the BG color is loaded in the BG plane 82

87 DCU layers background color Layers are memory areas that can reside in any memory. Internal or external FLASH or RAM. Size and position is configurable runtime in 1 pixel increments. The 2 highest priority layers support a special safety mode. Data in layers is coded in 1,2,4,8 bits per pixel or Raw color 16, 24, 32 bpp or.. (RGB565, RGB888, ARGB8888, ARGB1555, ARGB4444) or 4 or 8bpp transparency with foreground and background color or 4 or 8bpp luminance offset. 87

88 DCU CLUT CLUT is a color look up table. Size is 2k 24bpp colors, CLUT is assigned on a per layer basis. Pallet size is dynamic and is shared by all layers. Color depth is fixed to 24bpp RGB888 Layer control descriptor uses a color offset value to mark start position in the CLUT. As an example the CLUT can hold 8 x 8bpp pallets with 24bit colors. Or any combination required for the other indexed modes i.e. 1, 2, 4bpp. Run time manipulation and assignment of CLUT to a layer is possible. CLUT is part of the DCU memory and does not load the system memory bus. 88

89 MPC5606S, DCU timing example A B C 1 frame = 60Hz D A Layer CD s are latched in shadow buffer and frame composition starts. B CPU writes CD registers to prepare the next frame. Typically less than 0,1ms. Needs to be done within the frame period. C edma performs a ROM to RAM scan synchronized BLIT of the next car and navigation object. (Direct un-buffered frame synchronized blit) D edma performs vertical blanking period blit of CLUT, objects, HWC etc.. * C & D ie. the DMA activation is performed in ISR. * B The main frame loop is assumed to be a pre-emptive low priority task. Very relaxed latency requirement. Typically need <5% CPU as an average measured over 16ms. 89
