GPIO寄存器描述 《STM32参考手册中文-p75》
1、端口配置低寄存器(GPIOx_CRL)(x = A...E)
2、端口配置高寄存器(GPIOx_CRH)(x = A...E)
3、端口输入数据寄存器(GPIOx_IDR)(x = A...E)
这些位为只读并只能以字(16位)的形式读出。读出的值为对应I/O口的状态。
4、端口输出数据寄存器(GPIOx_ODR)(x = A...E)
只能以字(16bit)的形式操作，复位值全是0。写0即输出0，写1即输出1。
5、端口位设置/清除寄存器(GPIOx_BSRR)(x = A...E)
高16bit写1用于清0，低16bit写1用于置位，同时写1的话低16bi有效。
6、端口位清除寄存器(GPIOx_BRR)(x = A...E)
低16位写1用于置位。
7、端口配置锁定寄存器(GPIOx_LCKR)(x = A...E)
GPIO八种模式
