ADV7611 PASS THROUGH MODE

Question asked by kawamura on May 29, 2015

I want to know about the setting for ADV7611 PASS THROUGH MODE.

 

In the ADV7611 Hardware User Guide (UG-180) P.86, the following sequence is stated.

4:2:2 Pass Through

*Set DPP_BYPASS_EN to 1 to use the CP CSC

*Set UP_CONVERSION_MODE to 0

*Set DS_WITHOUT_FILTER to 0

*Configure the pixel output formatter to output a 4:2:2 stream (refer to the Pixel Port Output Modes section)

 

I can find the address for these register in P.86-87.

*DPP_BYPASS_EN, Addr 44 (CP), Address 0xBD[4]

*UP_CONVERSION_MODE, Addr 68 (HDMI), Address 0x1D[5]

*DS_WITHOUT_FILTER, Addr 40 (IO), Address 0xE0[7]

 

But I can not find in the ADV7611_Software_Manual(except UP_CONVERSION_MODE).

 

 

<Question>

1. Is the Addr 40(IO) for "DS_WITHOUT_FILTER" typo?  Addr 98(IO) is correct?

 

2. For the 4:2:2 Pass Through, the following setting is correct?

*Addr 44 Address 0xBD Data 0x18

*Addr 68 Address 0x1D Data 0x00

*Addr 98 Address 0xE0 Data 0x00

 

3. Are these Data is default value for ADV7611?

 

4. Can I get the latest ADV7611_Software_Manual which states these registers?

 

 

Sincerely

KAWAMURA
