ADV7181C unidentified Registers

In this file:

 

ADV7181C_ADV7181C@_ADV7341-VER.3.2c.txt

 

one can find several scripts with values to set on registers in order to work with evaluation board.

 

I've converted the first script of this file into a C data, however some of the registers (the ones with !!!!!):

 

  { 0x00 ,0x05 }, //; CVBS IN

  { 0x03 ,0x0C }, //; 8 Bit Mode

  { 0x04 ,0x77 }, //; Enable SFL

  { 0x17 ,0x41 }, //; select SH1

  { 0x1D ,0x47 }, //; Enable 28MHz Crystal

  { 0x31 ,0x02 }, //; Clears NEWAV_MODE, SAV/EAV  to suit ADV video encoders

  { 0x3A ,0x17 }, //; Set Latch Clock & power down ADC 1 & ADC2 & ADC3

  { 0x3B ,0x81 }, //; Enable internal Bias

  { 0x3D ,0xA2 }, //; MWE Enable Manual Window, Colour Kill Threshold to 2

  { 0x3E ,0x6A }, //; BLM optimisation !!!!!

  { 0x3F ,0xA0 }, //; BGB !!!!!

  { 0x86 ,0x0B }, //; Enable stdi_line_count_mode

  { 0xF3 ,0x01 }, //; Enable Anti Alias Filter on ADC0

  { 0xF9 ,0x03 }, //; Set max v lock range !!!!!

  { 0x0E ,0x80 }, //; ADI Recommended Setting

  { 0x52 ,0x46 }, //; ADI Recommended Setting

  { 0x54 ,0x00 }, //; ADI Recommended Setting

  { 0x7F ,0xFF }, //; ADI Recommended Setting

  { 0x81 ,0x30 }, //; ADI Recommended Setting !!!!!

  { 0x90 ,0xC9 }, //; ADI Recommended Setting

  { 0x91 ,0x40 }, //; ADI Recommended Setting

  { 0x92 ,0x3C }, //; ADI Recommended Setting !!!!!

  { 0x93 ,0xCA }, //; ADI Recommended Setting !!!!!

  { 0x94 ,0xD5 }, //; ADI Recommended Setting !!!!!

  { 0xB1 ,0xFF }, //; ADI Recommended Setting

  { 0xB6 ,0x08 }, //; ADI Recommended Setting !!!!!

  { 0xC0 ,0x9A }, //; ADI Recommended Setting

  { 0xCF ,0x50 }, //; ADI Recommended Setting !!!!!

  { 0xD0 ,0x4E }, //; ADI Recommended Setting !!!!!

  { 0xD1 ,0xB9 }, //; ADI Recommended Setting !!!!!

  { 0xD6 ,0xDD }, //; ADI Recommended Setting !!!!!

  { 0xD7 ,0xE2 }, //; ADI Recommended Setting !!!!!

  { 0xE5 ,0x51 }, //; ADI Recommended Setting

  { 0xF6 ,0x3B }, //; ADI Recommended Setting !!!!!

  { 0x0E ,0x00 }, //; ADI Recommended Setting

 

don't seem to exist or at least they are not described in the ADV7181C revision C manual (ADV7181C_Manual_RevC.pdf) page 206 to 210.

 

Are these registers described elsewhere? Are they hidden features?

 

thanks
