23 / 48 page  AD9389 Rev. 0 | Page 23 of 48 Hex Address Read/Write or Read Only Bits Default Value Register Name Description [1] ******0* VFE_input_edge Video data input edge. Defines the first clock edge of video word clocked. 0 = rising edge. 1 = falling edge. Default = 0 (in reference to DDR). [0] *******0 VFE_input_cs Video input color space. 0 = RGB. 1 = YCbCr. Default = 0. [7] 0******* itu_error_correct_en ITU656 error correction. This must be enabled if using ITU656 format. 0 = disable. 1 = enable. Default = 0. [6] *0****** itu_vsync_pol VS polarity from regenerated ITU 656 input. 0 = high polarity. 1 = low polarity. Default = 0. [5] **0***** itu_hsync_pol HS polarity from regenerated ITU 656 input. 0 = high polarity. 1 = low polarity. Default = 0. [4:3] ***00*** csc_mode Sets the fixed point position of the CSC coefficients, including the a4, b4, and c4 offsets. 00 = ±1.0, (from −4096 to +4095). 01 = ±2.0, (from −8192 to +8190.) 1× = ±4.0, (from −16,384 to +16,380). Default = 000. [2] *****0** gen_444_en 4:2:2 to 4:4:4 upconversion mode. 1 = uses interpolation. 0 = no interpolation. Default = 0. [1] ******0* ASP_ratio Aspect ratio of input video. 0 = 4:3. 1 = 16:9. Default = 0. 0x17 Read/Write [0] *******0 deGen_en Enable DE generator. The DE generator should be enabled when a DE input is not provided. 1 = enable DE generator. Default = 0 (see Register 0x30 to Register 0x3A). 0x18 Read/Write [4:0] ***00110 CSC_A1_MSB MSB of 0x19. 0x19 Read/Write [7:0] 01100010 CSC_A1_LSB Color space converter (CSC) coefficient for equation: ROUT = (a1 × RIN) + (a2 × GIN) + (a3 × BIN) + a4 GOUT = (b1 × RIN) + (b2 × GIN) + (b3 × BIN) + b4 B B OUT = (c1 × RIN) + (c2 × GIN) + (c3 × BIN) + c4 0x1A Read/Write [4:0] ***00100 CSC_A2_MSB MSB of 0x1B. 0x1B Read/Write [7:0] 10101000 CSC_A2_LSB CSC coefficient for equation: ROUT = (a1 × RIN) + (a2 × GIN) + (a3 × BIN) + a4 GOUT = (b1 × RIN) + (b2 × GIN) + (b3 × BIN) + b4 B B OUT = (c1 × RIN) + (c2 × GIN) + (c3 × BIN) + c4 0x1C Read/Write [4:0] ***00000 CSC_A3_MSB MSB of 0x1D. 0x1D Read/Write [7:0] 00000000 CSC_A3_LSB CSC coefficient for equation: ROUT = (a1 × RIN) + (a2 × GIN) + (a3 × BIN) + a4 GOUT = (b1 × RIN) + (b2 × GIN) + (b3 × BIN) + b4 B B OUT = (c1 × RIN) + (c2 × GIN) + (c3 × BIN) + c4 0x1E Read/Write [4:0] ***11100 CSC_A4_MSB MSB of 0x1F. |
