STM32N6570 OTP配置可是个头函数来配置如下：

ifndef NO_OTP_FUSE

/**

• @brief User OTP fuse Configuration

• The User Option Bytes are configured as follows :

  • VDDIO_HSLV = 1 (enable the configuration of pads below 2.5V,

    • I/O speed otpmization at low-voltage allowed)

      • XSPI1_HSLV = 1 (enable I/O XSPIM Port 1 high-speed option)

        • XSPI2_HSLV = 1 (enable I/O XSPIM Port 2 high-speed option)

          • Other User Option Bytes remain unchanged

            • @retval None */

          还可以使用CubeProgrammer来配置（注意更新CubeProgrammer最新版本）。
