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.
