Hi,Sir:

We are using the PF8100 with i.MX8QM.

And in the test of PF8100'reset time, we regard that the treg2reset should be the time between the LDO2_EN and reset_mcu. It's all right?

And after test, we got the test time of treg2reset should be 2.5mS> 1.5ms which be defind in Datasheet. So it shoulbe be problem? And we can adjust the time?

Pls advise,TKs!
