Hi,

I have a problem.

In SH4, when DMA operation is finished, interrupt priority can be only set
in IPRC register.
But, using InterruptAttach() or InterruptAttachEvent(), Interrupt Vector
number is needed.

How is Internal Interrupt’s interrupt vector number assigned?

Thanks

Do you mean the on-chip interrupt ?
