    I use the ATV Benchtop software to control the EVAL-ADV739x board, AD7403_xc3s400_adv7391-VER.1.2.c. I choose the setting of ##SD## : AUTODETECT NTSC/PAL/SECAM 10-Bit 422 out through encoder. I found some of the value of register is not as same as it in the **.txt. And some of the registers have two same address but different value.


In the  **.txt the value of address 52 is 0x46, but it shows 0xC8. There are two address 98, address 99 .... One is read only, another is write only. I write a new value to the write only one, and then read the read only one, the value is not the value which is I write. So why ?
