I have problem with DMA SCI on receiver idle interrupt.


I wrote the codes of SCI receiver by DMA  and it works well.


But when I try to add receiver idle interrupt, I can not find where the receiver idle interrupt vecteor is.

I have to search the whole <MC56F847xx Reference Manual> but no more information except bellows:


At the middle-left of the Figure 35-28,  there is a receiver idle interrupt Request.

But it does not exist in Table 3-10. Interrupt Vector Table:

And I can not find any relative information in CodeWarrior PE.


Please help me, thanks.
