Either: (a) we looked at the documentation for the hardware, which told us that this SoC is built with its Cortex-M core configured with that many interrupt lines Or: (b) this is for legacy reasons a bogus setting which happens to work because it's too big rather than too small For a new SoC, you need to follow course (a), ie look at what the hardware is and model that. -- PMM
