Tool/software:
The TRM refers to spruim2g.pdf.
In the TRM, "6.2.3.5.8.2 Servicing IRQ Through MMR Interface," it says, "When an IRQ interrupt is received, the CPU should follow these steps if not using the vector interface:."
When using the vector interface, I understand that the current interrupt processing method refers to a vector table registered in advance, and the interrupt processing routine is called and processed.
Therefore, I understand that the "vector interface" is an interface with interrupt processing using a vector table, but is this understanding correct?
If the above understanding is correct, I would like to know how the interrupt processing can be executed in the text "if not using the vector interface," as I do not understand it.
Thank you in advance for your help.
