Hi team,

Could you tell me which DIA_EN pin float or connected to ground through RPROT is better option considering noise?

In the case DIA_EN is not used, I guess using RPROT is better due to noise improvement, is it correct?

Ochi-san,

The DIA_EN pin has an internal pulldown so leaving it floating or grounding it is inconsequential for noise considerations. The recommendation is to leave it floating.
