TMS320F280049C: Why is the default interrupt handler preceded by a static modifier

Will Gao said:

Why does driverlib do this ? 

I agree that is odd.

The driverlib.h has a reference to Interrupt_defaultHandler in:

static inline void
Interrupt_unregister(uint32_t interruptNumber)
{
    uint32_t address;

    //
    // Calculate appropriate address for the interrupt number
    //
    address = (uint32_t)PIEVECTTABLE_BASE +
              (((interruptNumber & 0xFFFF0000U) >> 16U) * 2U);

    //
    // Copy default ISR address into PIE table
    //
    EALLOW;
    HWREG(address) = (uint32_t)Interrupt_defaultHandler;
    EDIS;
}

Presumably Interrupt_defaultHandler should be a non-static function in interrupt.c, with a function prototype in interrupt.h

Thanks for pointing this out. Will raise an issue for this and try to get it addressed in the next release of C2000Ware.
