+ ==============================================================================
+ ##### 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();
+
+ @endverbatim
