S12XE TIM Input Capture

[rayhall]

Hello,

I cannot get the TIM input capture interrupt to work. I have a square wave signal connected to pin PP0. I want an interrupt on both edges.

I have made a simple test project. I have attached the code.

Please do not mark this question as "Assumed Answered" until I confirm the answer is correct or solved.

Thank you,

Ray.

Have a look at PTRRR register. By default TIM is routed to port R.

Edward,

Thank you. I am using the 144 pin S12XE so it has no Port R.

I have attached the working version as it may help others.
