Recently, I start to use RT1050 EVK, based on SDK PIT driver example I plan to make a time delay function(with PIT). I found there is a problem on the delay function.
1. if I want to delay 1us, I will get the nearly 2 us delay, that is OK because there is interrupt head.
2. if I want to delay 480us, I will get the around 160us delay (check with scope).
3. when I set the delay as 5000us, I got 1800us delay.
The attached is the project source file(MCUXpresso project). Please advise me what is the problem to use PIT.
