    Hi,

    I'm developping a new application on a new (for me) controller ST7FOXK1.

    I use the Lite Timer RTC interrupt to manage timing function. I want to also use port A external interrupt to manage I/O.

    My problem is that if the external interrupt occur during the Lite Timer interrupt, my program stop and stay stopped?

    I've tryed to set a highest priority to LTC interrupt than on the external interrupt using ISPR registers but it doesn't works?

    I'm not able to mask the external interrupt while my counter is decremented by the LTC interrupt?

    Any help is welcome!
