MSP430F67641A: MSP430F67641A

Part Number: MSP430F67641A

Hi,

We are using MSP430F67641A Micro controller. In this when we use debugger mode then RTC vector interrupt does not respond.

For this we have to do Hard Reset, then this Interrupt starts.

Even Some time after getting in LPM mode in/out also this interrupt stops responding.

Kindly Suggest.

    Hi,

    can you give some more details on your application?

    Also, are all interrupts enabled that you need? Please check the MSP430x5xx and MSP430x6xx Family User's Guide for the correct register settings in Section 24.4.

    Could  it be possible, that one of the RTC interrupt flags with higher priorities is a set through register configuration so you don't see the interrupt coming that you're waiting for?

    If you see that this behaviour is linked to switching between LPM and AM, can you make sure that the right interrupts are always enabled when needed?

    You could also try to verify if the issue disappears while you're not in debug mode: You could use blinking LEDs or logging within the RTC isr to signalize the interrupt is being handled.

    Please share some of your findings and more application details to further troubleshoot your issue.

    Thanks and best regards,

    Britta
