Hi all

 

Let me confirm about the usage of SNVS_TAMPERx pins.

 

Q1.

According to the table 97 and 100 in datasheet, the Power Group of those pins are VDDD_SNVS_1P8_CAP.

It should connect to VDDD_SNVS_1P8_CAP when user do external pull-up.

Am I correct ?

 

I'm referring the following document.

Q3.

Could you tell me the Voh and Vol value of SNVS_TAMPERx pin when user use it as a output ?
