我在我的程序中绑定了两个中断：interrrupt 4和interrupt 5。其中interrrupt 4可以生效，interrupt 5不能生效。
有两点是可以确认的：
1.触发每个中断的事件是都产生了的
2.INTMUX1中设置的值是对的
以下是interrupt vector table 的创建，想请教下有什么思路来定位这个问题？多谢！
;create interrupt vector table for C6000 DSP
;--------------------------------------------------------------
;This file can be modified to add Interrupt Service Routine(ISR)
;for an interrupt, the steps are:
;1,reference to the externally defined ISR, for example
; .ref EDMA_ISR
;2,modify the corresponding entry in the interrupt vector table.
; For example, if interrupt 8 is used for EDMA, then you should
; modify the entry number 8 like below:
; VEC_ENTRY EDMA_ISR ;interrupt 8
