如何產生software interrupt?

You can reference demo-int under Andesight200MCU/demo/startup.
In interrupt.c of demo-int, the following statement can generate an SW interrupt.

Code:
void gen_swi()
{
    unsigned int int_pend;
    int_pend = __nds32__mfsr(NDS32_SR_INT_PEND);
    int_pend |= 0x10000;
    __nds32__mtsr(int_pend, NDS32_SR_INT_PEND);
    __nds32__dsb();
}
