C6655 GPIO中断配置中的GPIO管脚和事件对应关系



您好:

    我想咨询GPIO管脚的状态和事件如何对应上,

手册上有这样的对应关系

72 GPINT2 GPIO interrupt

73 GPINT3 GPIO interrupt

78 GPINT4 GPIO interrupt

79 GPINT5 GPIO interrupt

80 GPINT6 GPIO interrupt

...

89 GPINT15 GPIO interrupt

91 GPINTn  Local GPIO interrupt


这个意思是GPIO2就对应72号事件,GPIO3就对应73号事件吗? 为什么没有GPIO0 GPIO1 ?

还有就是GPINTn 91号事件 是做什么用的。
