6678中断的问题



我看了csl下的例子,下面这句不是很懂

intcContext.eventhandlerRecord = EventHandler;
intcContext.numEvtEntries = 10;
if (CSL_intcInit(&intcContext) != CSL_SOK)
{
System_printf("Error: GEM-INTC initialization failed\n");
return;
}

我弄不明白这个numEvtEntries = 10代表什么,我看了一下system interrupt3映射到channel3,而cicout3对应的是63号,又将63与中断vector4连接,但是一直没弄明白这个10是啥
