Hi, I am reading MPC8280 PowerQUICC=99 II Family Reference Manual. In section 4.3.1.1, it mentioned two words: grouped, spread. the sentence is like this: The SIU interrupt configuration register (SICR), shown in Figure 4-10, defines the highest priority interrupt and whether interrupts are grouped or spread in the priority table,
I have some trouble to understand this.
what is grouped? what is spread?
