Hi,

As the following figure shows, there is a POR inside PMC, but the voltage names been detected are different. Is the voltage VDD_CORE2 or VDD_CORE? Does VDD_CORE2 means standby domain VDD?

Hi,

Looking it from this point, we may have answered to fast.

Let us verify if it is indeed a typo (which should be, given there is no more information given on this signal). If so, to which pin it is referring (given it is referring to the STBY domain, we suspect it is VDD_STBY).

We do apologize for this situation.

Please, let us know.

Hi,

Seems to be a typo on the reference manual. You can see on the "Glossary" down below that VDD_CORE2 is not shown. Instead, VDD_STBY is the one mentioned.

Given that you are on the Standby domain, we should expect that VDD_STBY is the supply related to it. Even on the IOMUX provided on the RM, there is no reference over VDD_CORE2.

We do apologize for this inconvenience.

Please, let us know.

Hi,

Thanks for your reply.

So the Coarse POR inside PMC means SPD(Supply Present Detection), and this SPD detects VDD_STDY, not VDD_CORE?
