Part Number:ADS7961-Q1

We are using ADS7961 in manual mode interfacing with TMS320f28377D IC on SPI 

To configure the ic in Manual mode 0x1000 (channal 0 selected ) value is used  and i  m reading individual channal.

for chn0, chn1, chn3 and chn7  i m getting perfect result but for other channels such as 2,4,5,6,8 on-word i m getting wrong result.

follwoing is the values send in txbuf for n th frame and we r getting result in n+2 frame for selected channel .

chn0 = 0x1000; chn1 =0x1080;  chn2=0x1100; chn3=0x1180; chn4=0x1200;  etc 

Thanks in advance

Uma
