-The OPT_OS_NONE option is the only option which requires an MCU specific function. It needs `tusb_hal_millis` to measure the passage of time. On ARM this is commonly done with SysTick. The function returns the elapsed number of milliseconds since startup.

-`tusb_hal_millis` is also provided in `hw/bsp/<board name>/board_<board name>.c` because it may vary with MCU use.

 ### Device API
 
 After the USB device is setup, the USB device code works by processing events on the main thread (by calling `tud_task`). These events are queued by the USB interrupt handler. So, there are three parts to the device low-level API: device setup, endpoint setup and interrupt processing.

+  *            After Reset the Cortex-M4 processor is in Thread mode,

+  *                - Set the vector table entries with the exceptions ISR address,
+  *                - Configure the clock system  
+  *                - Branches to main in the C library (which eventually
+  *                  calls main()).
+  *            After Reset the Cortex-M4 processor is in Thread mode,
+  *            priority is Privileged, and the Stack is set to Main.

+  * @brief     STM32F328xx device vector table for GCC toolchain.
+  *            This module performs:
+  *                - Set the initial SP
+  *                - Set the initial PC == Reset_Handler,
+  *                - Set the vector table entries with the exceptions ISR address,
+  *                - Configure the clock system  
+  *                - Branches to main in the C library (which eventually
+  *                  calls main()).
+  *            After Reset the Cortex-M4 processor is in Thread mode,
+  *            priority is Privileged, and the Stack is set to Main.

+  *                - Branches to main in the C library (which eventually

+  *            After Reset the Cortex-M4 processor is in Thread mode,

+  * @brief   CMSIS Cortex-M4 Device Peripheral Access Layer System Source File.
+  *
+  * 1. This file provides two functions and one global variable to be called from
+  *    user application:
+  *      - SystemInit(): This function is called at startup just after reset and 
+  *                      before branch to main program. This call is made inside
+  *                      the "startup_stm32f3xx.s" file.
+  *
+  *      - SystemCoreClock variable: Contains the core clock (HCLK), it can be used
+  *                                  by the user application to setup the SysTick
+  *                                  timer or configure other parameters.
+  *
+  *      - SystemCoreClockUpdate(): Updates the variable SystemCoreClock and must
+  *                                 be called whenever the core clock is changed
+  *                                 during program execution.
+  *
+  * 2. After each device reset the HSI (8 MHz) is used as system clock source.
+  *    Then SystemInit() function is called, in "startup_stm32f3xx.s" file, to
+  *    configure the system clock before to branch to main program.
+  *
+  * 3. This file configures the system clock as follows:
