+  * @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

+                    ##### 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();
