How to clear RESETREAS

[JIYEON]

Hello,

I am trying to clear reset reason when it wake-up by GPIO.

In line 163, I set RESETREAS to 0

In line 164, RESETREAS is read again.

I expect 0. But It still 0x00010004.

How could I reset register?

Hi,

 

This register is cleared by writing '1' to the specific bits that are set:
