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

- ==============================================================================\r
- ##### How to use this driver #####\r
- ==============================================================================\r
- [..]\r
- The PCD HAL driver can be used as follows:\r
-\r
- (#) Declare a PCD_HandleTypeDef handle structure, for example:\r
- PCD_HandleTypeDef hpcd;\r
-\r
- (#) Fill parameters of Init structure in HCD handle\r
-\r
- (#) Call HAL_PCD_Init() API to initialize the PCD peripheral (Core, Device core, ...)\r
-\r
- (#) Initialize the PCD low level resources through the HAL_PCD_MspInit() API:\r
- (##) Enable the PCD/USB Low Level interface clock using\r
- (+++) __HAL_RCC_USB_CLK_ENABLE(); For USB Device only FS peripheral\r
-\r
- (##) Initialize the related GPIO clocks\r
- (##) Configure PCD pin-out\r
- (##) Configure PCD NVIC interrupt\r
-\r
- (#)Associate the Upper USB device stack to the HAL PCD Driver:\r
- (##) hpcd.pData = pdev;\r
-\r
- (#)Enable PCD transmission and reception:\r
- (##) HAL_PCD_Start();\r
-\r
