Hello ,
We are using the auto sequence feature of the ADS8166 following the steps on page 34 of the datasheet to mimic figure 48. But after we issue the start command our SEQSTS pin never goes high. I see a note in SDO_CNTL4 that if you set the bit to 1 then it indicates the active status. I am not doing that in my code today and I am just relying on the auto sequence to automatically drive the SEQSTS pin. Is that wrong? Do I need to also program SDO_CNTL4 to 1 show the active status so that SEQSTS pin toggles? What does that statement mean in the SDO_CNTL4 register about active status?
Here is what I am writing to the registers:
Addr: 0x1C, value of 0x02 (dev_cfg)
Addr: 0x80, value of 0xFF (auto_seq_cfg1)
Addr: 0x82, value of 0x01 (auto_seq_cfg2)
Addr: 0x1E, value of 0x01 (start)
