  * @brief   PCD HAL module driver.
  *          This file provides firmware functions to manage the following 
  *          functionalities of the USB Peripheral Controller:
  *           + Initialization and de-initialization functions
  *           + IO operation functions
  *           + Peripheral Control functions 
  *           + Peripheral State functions
  *

                    ##### 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 HCD 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_CLK_ENABLE);
           
         (##) 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 HCD transmission and reception:
         (##) HAL_PCD_Start();
