    Hi manyam,

    It again depends on how your implementation is.

    As peter specified there are few peripheral interrupt controllers which keeps the interrupt status alive until you service/clear it.

    But as the general point, when you disabled in CPSR then there is no effect, the moment you unmask it then depending on the implementation it will be serviced or ignored.
