I'm confused about how the interrupt sources are mapped to the IRQSTEER. Here is a use case to illustrate:
I want the M4_0 to use LSIO GPT_4. The interrupt ID of GPT_4 is 167. I could experimentally figure out that this interrupt source #167 is routed to IRQSTEER_1 and becomes vector 33 to the M4 core. But how I derive 33 from 167?
I'd appreciate it if someone could elaborate on the process or point me to relevant documentation.
Thanking you in advance,
