NVIC interrupt

Hello,

 

Is it possible to force, by setting a bit somewhere, an interrupt on a NVIC_Reserved vector?

I see people asking, why he want to do that?.

Because, I use an ISR outside MQX at high frequency rate, and I need to set an lwevent when process is done, so I need to trigger by software an other interrupt (declared in MQX) performing the _lwevent_set.

It's a little bit tricky, but it respect real-time rules, and I already use this trick with coldfire V2.

I need to know how to access NVIC register.

 

I admit, NVIC is a big black box for me, if someone can give me some clues.

 

Thanks,

Emmanuel
