查看技术手册的章节:

30.5.1 SW_MUX_CTL_PAD_BOOT_MODE0 SW MUX Control
Register (IOMUXC_SW_MUX_CTL_PAD_BOOT_MODE0)

技术手册中
GPIO5的地址是
IOMUXC_SW_MUX_CTL_PAD_BOOT_MODE0

Address: 20E_0000h base + 14h offset = 20E_0014h

原子哥写的地址是:
#define IOMUXC_SNVS_BOOT_MODE0_GPIO5_IO10                   0x02290000U, 0x5U, 0x00000000U, 0x0U, 0x02290044U

IOMUXC_SW_MUX_CTL_PAD_SNVS_TAMPER0

Address: 20E_0000h base + 1Ch offset = 20E_001Ch
#define IOMUXC_SNVS_SNVS_TAMPER0_GPIO5_IO00                0x02290008U, 0x5U, 0x00000000U, 0x0U, 0x0229004CU

这个GPIO的地址为什么不是20E_xx
而是  220_xx的地址呢？
