Hello Sandeep san,
Our customer understood that Manual mode seaquence.
However , they wonder the Auto-1 mode seaquence now.
According to FIgure 50 and Figure 51 in the ADS7954 datasheet, similar seaquence between manual mode and Auto-1 mode.
But, our customer result is as below.
SDO data corresponds previous frame selected ch.
Is this reason that ‘Auto-1 mode programming’ for pre-programming the channel sequence" ?
-------------------
Ch setting is Ch0-Ch3
<in Frame n>
SDI : Channel counter set to min
<in Frame n+1>
SDI : increment
SDO : Ch 0 output
<in Frame n+2>
SDI: 0x0000 ( Continued operation in a select mode)
SDO : Ch 2 output
-------------------
Best Regards,
Ryuji Asaka
<in Frame n+3>
SDI: 0x0000 ( Continued operation in a select mode)
SDO : Ch 1 output
