W're using your ADC AD9265, We like to use its BIST feature to verify data lines. PN9 is used to test it, The number sequence captured are 073C, 2E44, 121C, A3CE...the numbers are repeated every 511 count. I don't know if the numbers captured are correct. May you help to give a PN9 sequence table? the seed value is 0x92 according to AD9265 datasheet. I could tell if the data line order is correct or not if I have your PN9 list to compare. thanks.
"010 = positive FS " and "011 = negative FS" and "111 = one/zero word toggle" could be verified successfully, but they can not tell if data bit order is correct.
073C is the first data after exiting from reset
the data is 0xFFFF during reset (0x0D=0x16)
sorry one typo error, 073C should be 033C
Read 0x25 always get 0x80, Read 0x24 always get 0xCF
