Hi all,

 

    I am testing External Interrupt function with TRK-KEA128 now, but there never trigger the isr so need help.

 

1) Using CW10.6, ProcessorExpert to generate ExInt

2) Could only choose PTI4 for input (why? datasheet says PTI0~PTI6 could be set)

3) Input waveform with 10KHz, 1us width, 5V amplitude.

 

   Any help is appreciated.
