Approved TD-240201SH DS 3.7.4 Texture D/AVE supports U/V clamp and U/V repeat. Also filtering for both axes separately is supported. The next table demonstrates these different options. x no filter filter clamp repeat clamp repeat y no filter filter clamp repeat clamp repeat Table 3-1 Texture examples Title D/AVE 2D Data Sheet Version 2.9 Date 2012-08-01 Sign Number TD-240201SH DS Author Christian Sehnke Page 20/42
Approved TD-240201SH DS 4. REGISTER DESCRIPTION Not all registers are described in full detail here as the interface to D/AVE 2D is considered to be the SW driver and not the register interface itself. 4.1 Control Registers Write: D2_CONTROL - Geometry control register D2_CONTROL2 - Surface control register D2_IRQCTL - Interrupt control register D2_CACHECTL - Cache control register Read: D2_STATUS - Status control register D2_HWREVISION - Hardware version and feature set ID 4.1.1 D2_CONTROL Offset: Default Value Access Description 0x00 0x00000000 Write Only This register controls the pixel enumeration and selection units, deciding which pixels are part of the geometry. A detailed description would not be understandable without deep knowledge of the internal rendering mechanism of D/AVE 2D and is therefore not provided. Table 4-1 Register: D2_CONTROL 4.1.2 D2_CONTROL2 Offset: Default Value Access Description 0x01 0x00000000 Write Only This register controls the colorization and blending units, deciding what color a pixel should have. Name Bits Description D2C_RLE_PIXEL_WIDTH 31:30 Width of a texel for the RLE unit: 0..3 = 1-4 bytes per texel. D2C_BDIA 29 If D2C_USE_ ACB = 1: 0 = use blend factor as specified by D2C_BDFA 1 = invert destination blend factor (1-x) D2C_BSIA 28 If D2C_USE_ ACB = 1: 0 = use blend factor as specified by D2C_BSFA 1 = invert source blend factor (1-x) D2C_CLUTFORMAT 27 0 = ARGB8888 (default) 1 = RGB565 D2C_COLKEY_ENABLE 26 Enable the color keying unit. D2C_CLUT_ENABLE 25 Enables the CLUT. If CLUT is not enabled for an indexed format, the index will be directly put on the Title D/AVE 2D Data Sheet Version 2.9 Date 2012-08-01 Sign Number TD-240201SH DS Author Christian Sehnke Page 21/42
