Which Status Bit in RTI determines the occurence of CAPTURE Event

Hello Pashan,

  There is a no status bit to indicate the completion of the capture event. Whenver an event is detected the RTI will take the timestamp of the up counter and the free running counter and save them into the RTICAUCx and RTICAFRCx. So it is possible that if you have a extremely fast event frequency then the  RTICAUCx and RTICAFRCx are overwritten with new values before CPU reads them.

Hello Charles,

So, how do I detect whether the RTI CAPTURE have occurred at all or not?

Which FLAG in the system will tell me that one CAPTURE event have occurred within RTI?

Thank you.

Pashan

Hello Pashan,

  There is no such flag to indicate that the RTI had just moved the up/free counter values to the  RTICAUCx and RTICAFRCx due to an incoming capture event from the VIM. Can you poll the capture registers and compare with  the previous timestamp that you might have saved in the memory and if there is a difference then it means a new event has arrived?
