GPIO的地址对应问题

Other Parts Discussed in Thread: CC3200

CC3200的第50PIN,也就是GPIO0,规格书上Pin Multiplexing表格写的是0x4402 E0A0,可程序例子定义#define GPIOA0_BASE             0x40004000,请问这二者之间有什么联系吗?

  • joey,

      GPIOA的寄存器base存储区域是0x40004000,没错,你看到的0x4402 E0A0是我们芯片的pinmultiplexing功能配置的寄存器的存储地址。

    两个是完全独立的寄存器地址。前面一个用于配置GPIO的常规应用功能的,后面是配置管脚复用的。



    谢谢
