Dear community,
I have a question about power-up sequence about VDD_HIGH_IN .

 

[Background]
In the datasheet , it is described that
VDD_SNVS_IN supply must be turned ON before any other power supply. It may be connected
(shorted) with VDD_HIGH_IN supply.

I did not see any sequence requirements on VDD_HIGH_IN.

 

[Question]
When VDD_SNVS_IN is connected with VDD_HIGH_IN ,
does the VDD_HIGH_IN have to  turned on before any other power supply ?

 

Best Regards,
Koichi Sakagami
