HELLO

HERE'S A PROBLEM WITH KBI MODULE. AS WE KNOW KBI CAN BE SET UP FOR RISING EDGE / FALLING EDGE TRIGGER. BUT IF I USE KBI FOR A SWITCH WITH SETUP OF ACTIVE LOW HOW CAN I KNOW WHEN USER RELEASE THE SWITCH? I MEAN WHEN USER IS PUSHING BUTTON WE CAN THROUGH INTERRUPT FLAG TO CONFIRM THE STATUS BUT CANNOT RECOGNIZE THE RELEASE FROM BUTTON.

 

WE DON'T WANT TO USE A METHOD OF FOR LOOP BY POLLING. IT WASTE THE PERFORMANCE OF CHIP. WE WANT HARDWARE DETECTION LIKE FTM CAPTURE IN.
