Hi, Thank you showing othe post.

Degital cell circuit is always driven by DEC1 regulator, not by 1.3V regulator, is it correct ?

Hi,

Yes, the digital interface is always powered by the (1.1 V - 0.9 V) regulator that is connected to DEC1. But that regulator is preceded by the 1.3 regulator that is connected to DEC4.
