Why not use Ch0 of the timer to capture rising and Ch1 of the timer falling?

Hi Dirty Harry ,

you are right, but if i do that, i should assign two pins for timer.

thank you!

You could set the timer for input capture. Any edge will set a flag and trigger an interrupt.

This information is in swru191c page 109-110. CC253x/CC254x User Guide.

you read the state of the port pin. if it is low, it was a falling edge. if it is high, a rising edge.
