                  ##### How to use this driver #####
==============================================================================
  [..]
    The PCD HAL driver can be used as follows:

   (#) Declare a PCD_HandleTypeDef handle structure, for example:
       PCD_HandleTypeDef  hpcd;

   (#) Fill parameters of Init structure in HCD handle

   (#) Call HAL_PCD_Init() API to initialize the PCD peripheral (Core, Device core, ...)

   (#) Initialize the PCD low level resources through the HAL_PCD_MspInit() API:
       (##) Enable the PCD/USB Low Level interface clock using
            (+++) __HAL_RCC_USB_OTG_FS_CLK_ENABLE();
            (+++) __HAL_RCC_USB_OTG_HS_CLK_ENABLE(); (For High Speed Mode)

       (##) Initialize the related GPIO clocks
       (##) Configure PCD pin-out
       (##) Configure PCD NVIC interrupt

   (#)Associate the Upper USB device stack to the HAL PCD Driver:
       (##) hpcd.pData = pdev;

   (#)Enable PCD transmission and reception:
       (##) HAL_PCD_Start();
