I found ''TLI'' in the special features of ST72324 of ST MCU selection guid.

I don't know the meaning of ''TLI'', can anyone tell me.

Thanks

TLI means Top Level Interrupt.

Each interrupt has it's own priority (software and hardware priority) and the TLI is the highest

That means the interrupt of MCU with TLI features is nested, right?

Yes Terry

Some ST MCU can work in both in concurrent or nested mode.

In concurrent mode interrupt can't be interrupted by another however nested mode allow the interruption

.

Be care full of stack overflow in nested mode .
