大家好,
请问(0,4,8,12)是否有特殊含义?为什么第一列被写为(0,4,8,12)而不是GPIOx?谢谢。

祝好,
Zijian

说实话,我也对这个描述有点迷,手册上也没有相关说明。找到一个英文帖子讲了这个东西,应该是讲的比较明确的,你可以看一下:e2e.ti.com/.../ccs-tms320f28377d-what-does-gpio-index-mean-in-datasheet-or-reference-manual
您好,
我已经懂了,0,4,8,12是将配置寄存器GPyGMUXn.GPIOz(两位)+GPyMUXn.GPIOz(两位)连在一起后换算成十进制的值,配置成0000,0100,1000和1100均可以将GPIOz配置为GPIO功能。
