调程序调了两天，连个管脚都搞不定，自己都怀疑是不是自己老了

终于对着官方的预编译和 RTT 的预编译找到了问题

问题如下：  下面看到的是官方RTT 原来提供的和我修改后的对比

/* GPIO3 */                                                                                 修改后的如下

可以通过官方的管脚预编译，证明RTT 给的是错误的：

#define IOMUXC_GPIO_EMC_41_ENET_MDIO 0x401F80B8U, 0x4U, 0x401F8430U, 0x1U, 0x401F82A8U
#define IOMUXC_GPIO_EMC_41_GPIO3_IO27 0x401F80B8U, 0x5U, 0, 0, 0x401F82A8U
#define IOMUXC_GPIO_EMC_41_USDHC1_VSELECT 0x401F80B8U, 0x6U, 0, 0, 0x401F82A8U

#define IOMUXC_GPIO_AD_B0_00_XBAR1_INOUT14 0x401F80BCU, 0x1U, 0x401F8644U, 0x0U, 0x401F82ACU
#define IOMUXC_GPIO_AD_B0_00_REF_CLK_32K 0x401F80BCU, 0x2U, 0, 0, 0x401F82ACU

在地址寄存器连续性上，GPIO_EMC_41 后面紧跟的是 GPIO_AD_B0_00    ，RTT 提供的GPIO_EMC_41 后面紧跟的为 GPIO_SD_B1_00
