Hi @jingfang,

It depends on the power supply ramp rate:

Once VDDX reaches 2.7V, which is the Low Voltage Reset Deassert threashold, the MCU leaves the system reset.

In the datasheet, you can find these specifications:

Hello @danielmartynek 
Thank you very much for your clarification. I have understood it.
But if can you tell me roughly, how much time it will take to jump to Application, when we normally Reset the MCU.
Actually I am achieving 4.22ms, for your kind reference I have attached Logic Analyzer image.
I hope you will correlate my doubts.

One more Doubts @danielmartynek  

Will you clarify my one Doubts, on the Datasheet the Flash Timing Specification for (Program Section
execution time) (1KB flash)  is 5ms.
So when the Micro-controller is Powered, does it is taking 5ms to jump into the Application Program?
For you kind reference I took snap from the datasheet. I hope you will check Flash Timing Specifications Image for it.

I hope to hear from you Soon

Hi @Nibesh,

Can you put it into a new thread?

This is not related to the subject of this thread.
