I am seeing an undershoot voltage around 1.25v for HTS221 while data transfer going on. Can you please help me to solve this issue.

Hi @JFran.2​ ,

are you referring to the circled in red? Are you sure they are undershooting of 1.25V? It looks to me it is the standard signature of the ACK (the slave that drives low the SDA line after master communication).

I'm not sure instead that the second clock sequence is correct: why is it not grouped in batches of 8-bits?

Hi Eleon,

I am not referring to that. Please see the attached image
