27 / 60 page ![]() AD9380 Rev. 0 | Page 27 of 60 Hex Address Read/Write or Read-Only Bits Default Value Register Name Description [1] ******1* Primary Output Enable Enables primary output. [0] *******0 Secondary Output Enable Enables secondary output (DDR 4:2:2 in Output Modes 1 and 2). 0x26 Read/Write [7] 0******* Output Three-State Three-state the outputs. [6] *0****** SOG Three-State Three-state the SOG output. [5] **0***** SPDIF Three-State Three-state the SPDIF output. [4] ***0**** I2S Three-State Three-state the I2S output and the MCLK out. [3] ****1*** Power-Down Pin Polarity Sets polarity of power-down pin. 0 = active low. 1 = active high. Selects the function of the power-down pin. [2:1] *****00* Power-Down Pin Function 00 = power-down. 01 = power-down and three-state SOG. 10 = three-state outputs only. 11 = three-state outputs and SOG. [0] *******0 Power-Down 0 = normal. 1 = power-down. 0x27 Read/Write [7] 1******* Auto Power-Down Enable 0 = disable auto-low power state. 1 = enable auto-low power state. [6] *0****** HDCP A0 Sets the LSB of the address of the HDCP I2C. Set to 1 only for a second receiver in a dual-link configuration. 0 = use internally generated MCLK. 1 = use external MCLK input. [5] **0***** MCLK External Enable If an external MCLK is used, then it must be locked to the video clock according to the CTS and N available in the I2C. Any mis- match between the internal MCLK and the input MCLK results in dropped or repeated audio samples. [4] ***0**** BT656 EN Enables EAV/SAV codes to be inserted into the video output data. [3] ****0*** Force DE Generation Allows use of the internal DE generator in DVI mode. [2:0] *****000 Interlace Offset Sets the difference (in HSYNCs) in field length between Field 0 and Field 1. 0x28 Read/Write [7:2] 011000** VS Delay Sets the delay (in lines) from the VSYNC leading edge to the start of active video. [1:0] ******01 HS Delay MSB MSB, Register 0x29. 0x29 Read/Write [7:0] 00000100 HS Delay Sets the delay (in pixels) from the HSYNC leading edge to the start of active video. 0x2A Read/Write [3:0] ****0101 Line Width MSB MSB, Register 0x2B. 0x2B Read/Write [7:0] 00000000 Line Width Sets the width of the active video line in pixels. 0x2C Read/Write [3:0] ****0010 Screen Height MSB MSB, Register 0x2D. 0x2D Read/Write [7:0] 11010000 Screen Height Sets the height of the active screen in lines. 0x2E Read/Write [7] 0******* Ctrl EN Allows Ctrl [3:0] to be output on the I2S data pins. 00 = I2S mode. [6:5] *00***** I2S Out Mode 01 = right-justified. 10 = left-justified. 11 = raw IEC60958 mode. [4:0] ***11000 I2S Bit Width Sets the desired bit width for right-justified mode. |
