我在对C6678执行Power Sleep Control的关核操作，按照Corepac User Guide中说明要执行如下操作：
1. Enable power-down by setting the MEGPD field to 1 in the PDCCMD register.
2. Enable the DSP interrupt(s) that you want to wake-up the C66x CorePac. Disable all other interrupts.
3. Execute the IDLE instruction.
请问第2步中的DSP interrupt是哪个中断 最好能够提供相应的代码，谢谢！！！
