I am a new to use the function of FlexPWM capture about MPC5643L. In the process of using, I had a promblem.
I use the PIN of D3 (A) as the input port to capture the signal，but every time signal capture faild. I have already achieced capture use the x[n]. who knows what is the difference between capture A/B[n] and capture x[n] .Thank you can provide source code and some information.
In the chip reference manual pin function table, I discover that this pin has a capture function. The following is a screenshot of my list from the chip reference manual .
The chip reference manual shows that flexPWM_0 about A  has a capture function. Now I do not know how to do it.
thank you very much for your help.
