Hi Sir,

 

    Since there is some register is hidden in ADV7283(like following register), so My customer ask that does ADI have more detail document that describe register statement and he could base on this to modify the video quality like sharpness etc....

 

/* accesses main register space */

{ REG_ADI_CONTROL_1, 0x00},

/* delay 10 ms */

{ 0x0A, 0x00},

/* system functional(exit power down)*/

{ REG_POWER_MANAGEMENT, 0x00},

/* ADI required write(this is a hidden register !!) */

{ 0x52, 0xCD},

/* CVBS input on Ain 4(CCD)*/

{ REG_INPUT_CONTROL, 0x03},

/* ADI required write */

{ REG_ADI_CONTROL_1, 0x80},

/* reset clamp circuitry[step 1](this is a hidden register !!*/

{ 0x9c, 0x00},

/* reset clamp circuitry[step 1](this is a hidden register !!*/

{ 0x9c, 0xFF},

/* accesses main register space */

{ REG_ADI_CONTROL_1, 0x00},

/* ADI required write(this is a hidden register !!) */

{ 0x80, 0x51},

/* ADI required write(this is a hidden register !!) */

{ 0x81, 0x51},

/* ADI required write(this is a hidden register !!) */

{0x82, 0x68},

/* output drivers enabled */

{REG_OUTPUT_CONTROL, 0x0C},

/* outputs SFL information on the SFL pin, */

REG_EXTENDED_OUTPUT_CONTROL, 0x07},

/* SH1 C filter */

{REG_SHAPING_FILTER_CONTROL_1, 0x41,

/* LLC pin active */
