2)       Timer (TB3) are configured to capture for external signal (P4.3)

3)       Input signal is stable

    I'm pretty sure that you also activated teh tiemr overflow intrrupt (TAIE bit in TACTL - this is NOT a requirement for getting capture interrupts, but a separate interrupt)

    And a timer overflow occurs every 65536 ticks (2 seconds on 32768Hz)

    OK! Jens-Michael Gross.

    Thank you for your respond (very soon!!! but with a little bit mistake).
    Im just test E2E service. I dont know what is it and how it works.

    About MSP-timer-capture - it doesnt matter
    but this problem - because CAP bit of TxCCTLx was not set properly.
    Timer overflow - less simular than Compare Interupt (each 65536 ticks).
