  * @brief   CMSIS Cortex-M0 Device Peripheral Access Layer System Source File.

			




	
	
	
		
 
  *

			




	
	
	
		
 
  * 1. This file provides two functions and one global variable to be called from

			




	
	
	
		
 
  *    user application:

			




	
	
	
		
 
  *      - SystemInit(): This function is called at startup just after reset and 

			




	
	
	
		
 
  *                      before branch to main program. This call is made inside

			




	
	
	
		
 
  *                      the "startup_stm32f0xx.s" file.

			




	
	
	
		
 
  *

			




	
	
	
		
 
  *      - SystemCoreClock variable: Contains the core clock (HCLK), it can be used

			




	
	
	
		
 
  *                                  by the user application to setup the SysTick

			




	
	
	
		
 
  *                                  timer or configure other parameters.

			




	
	
	
		
 
  *

			




	
	
	
		
 
  *      - SystemCoreClockUpdate(): Updates the variable SystemCoreClock and must

			




	
	
	
		
 
  *                                 be called whenever the core clock is changed

			




	
	
	
		
 
  *                                 during program execution.

			




	
	
	
		
 
  *

			




	
	
	
		
 
  * 2. After each device reset the HSI (8 MHz) is used as system clock source.

			




	
	
	
		
 
  *    Then SystemInit() function is called, in "startup_stm32f0xx.s" file, to

			




	
	
	
		
 
  *    configure the system clock before to branch to main program.

			




	
	
	
		
 
  *

			




	
	
	
		
 
  * 3. This file configures the system clock as follows:

  * @brief   This file provides the high layer firmware functions to manage the 

			




	
	
	
		
 
  *          following functionalities of the USB CDC Class:

			




	
	
	
		
 
  *           - Initialization and Configuration of high and low layer

			




	
	
	
		
 
  *           - Enumeration as CDC Device (and enumeration for each implemented memory interface)

			




	
	
	
		
 
  *           - OUT/IN data transfer

			




	
	
	
		
 
  *           - Command IN transfer (class requests management)

			




	
	
	
		
 
  *           - Error management

			




	
	
	
		
 
  *

  *          =================================================================== 

			




	
	
	
		
 
  *           This driver manages the "Universal Serial Bus Class Definitions for Communications Devices

			




	
	
	
		
 
  *           Revision 1.2 November 16, 2007" and the sub-protocol specification of "Universal Serial Bus 

			




	
	
	
		
 
  *           Communications Class Subclass Specification for PSTN Devices Revision 1.2 February 9, 2007"

			




	
	
	
		
 
  *           This driver implements the following aspects of the specification:

			




	
	
	
		
 
  *             - Device descriptor management

			




	
	
	
		
 
  *             - Configuration descriptor management

			




	
	
	
		
 
  *             - Enumeration as CDC device with 2 data endpoints (IN and OUT) and 1 command endpoint (IN)

			




	
	
	
		
 
  *             - Requests management (as described in section 6.2 in specification)

			




	
	
	
		
 
  *             - Abstract Control Model compliant

			




	
	
	
		
 
  *             - Union Functional collection (using 1 IN endpoint for control)

			




	
	
	
		
 
  *             - Data interface class

			




	
	
	
		
 
  * 

			




	
	
	
		
 
  *           These aspects may be enriched or modified for a specific user application.

			




	
	
	
		
 
  *          

			




	
	
	
		
 
  *            This driver doesn't implement the following aspects of the specification 

			




	
	
	
		
 
  *            (but it is possible to manage these features with some modifications on this driver):

			




	
	
	
		
 
  *             - Any class-specific aspect relative to communication classes should be managed by user application.

			




	
	
	
		
 
  *             - All communication classes other than PSTN are not managed

			




	
	
	
		
 
  *
