我想知道S32K3XX的中断数字与中断优先级之间的关系,数字越小中断优先级越小吗?请问我在参考手册的哪些地方能看到相关的描述?感谢!

Hi

数值越低,中断优先级越高。

Each priority field holds a priority value, 0-255. The lower the value, the greater the priority of the corresponding interrupt. If enabled, the processor can implement only bits[7:n] of each field, bits[n-x:0] read as zero and ignore writes. The values of n and x are implementation defined.
