32KHz crystal on Launch pad?

Hey all,

Is it possible to use the uC without this crystal stably? I mean without resetting itself from time to time.

Is it possible to use PWM and UART simultaneously since they use TIMER_A?

thank u

    Did you disable the Watchdog Timer? i.e.

    // disable watchdog timer
    //------------------------

    WDTCTL = WDTPW + WDTHOLD;               // Stop WDT

    Should be the first instruction of your application! If you will use it in your application you can re-enable it later!

    No, you need to stop the PWM for doing the UART communication and vice versa. If you need both simultaneously, you should use a device with a hardware UART or at least two timers.
