6678中断的问题

如果第一次进入中断函数，清中断后，还没执行完。此时又来了一个相同的中断。DSP是不是先执行完中断函数的程序再重新再进入中断。

user1534243：

If a new event is received during the same cycle, a clear is specified via an EVTCLRx
register, the new event input takes precedence as an additional precaution against
missing events.

是的。
It is also important to note that within the service routine, the appropriate event flag register bits must be cleared by software in order to receive a subsequent event. If the event flag(s) does not clear, then a new system event will not be recognized.

Shine：

是的，所以要避免这种情况发生，以免丢中断。
