Hello TQ san

For offset calibration, you will need 16 SCLK falling edges once CS goes low. This also requires to include setup time from CS falling to SCLK falling edge.

Regarding timing diagram there is error in the description. Your understanding is correct. For 8 bit device SDO will have first two bits zero followed by 8 bit conversion result.

Thanks for pointing this out. We will work on getting this corrected

Thanks & Regards

I understood that this means 15 SCLK.

My customer requires to modify the datasheet.
