Hi Shinnosuke,

Our recommendation is having a voltage ramp up directly from 0V.

Hi,

Thank you for your reply.

What kind of problem do you think?

I think there is no problem because RESET is released after VDD (+3.3V) became stable.

Best regards,

Shinnosuke

Hi Shinnosuke,

Logically, it should work as expected. However, we have not seen this issue before, so we are also not sure what might be the potential issue that this may bring up.

Sincerely,
