Carlo,

I will ask around, but I am not sure if there is an example of this.

We have a well written Wiki Page available on the topic: processors.wiki.ti.com/.../Interrupt_Nesting_on_C28x

Carlo,

I was mistaken. We do have an example in C2000ware:

Carlo,

The example demonstrates how to nest more than one level. In each interrupt higher priority interrupts are re-enabled allowing them to nest deeper than one level.
