/*******************************************************************************
List of Errors and Return values, Explanations and Help.
********************************************************************************

Error Name:   Flash_AddressInvalid
Description:  The address given is out of the Flash memory address range.
Solution:     Check whether the address given is in the valid Flash memory address range.
********************************************************************************

Error Name:   Flash_PageEraseFailed
Description:  The Page Erase instruction did not complete successfully.
Solution:     Try to erase the Page again. If the operation fails again, the device
              may be faulty and need to be replaced.
********************************************************************************

Error Name:   Flash_PageNrInvalid
Note:         The Flash memory is not at fault.
Description:  An attempt to select a Page (Parameter) that is not
              within the valid range has been made. Valid Page numbers are from 0 to
              FLASH_PAGE_COUNT - 1.
Solution:     Check that the Page number given is in the valid range.
********************************************************************************

Error Name:   Flash_SectorNrInvalid
Note:         The Flash memory is not at fault.
Description:  An attempt to select a Sector(Parameter) that is not
              within the valid range has been made. Valid Sector numbers are from 0 to
              FLASH_SECTOR_COUNT - 1.
Solution:     Check that the Sector number given is in the valid range.
********************************************************************************

Return Name:  Flash_FunctionNotSupported
Description:  The user has attempted to make use of a functionality not
              available on this Flash device (and thus not provided by the
              software drivers).
Solution:     This may happen after changing Flash SW Drivers in existing
              environments. For example an application tries to use a
              functionality that is no longer provided with the new device.
********************************************************************************

Return Name:  Flash_NoInformationAvailable
Description:  The system cannot give any additional information about the error.
Solution:     None
********************************************************************************

Error Name:   Flash_OperationOngoing
Description:  This message is one of two messages which are given by the TimeOut
              subroutine. That means that the current Flash memory operation is still
	      within the defined time frame.
********************************************************************************

Error Name:   Flash_OperationTimeOut
Description:  The Program/Erase Controller algorithm could not complete an
              operation successfully. It should have set bit 7 of the Status
              Register from 0 to 1, but this did not happen within the predefined
              time limit. The operation was therefore cancelled by a timeout.
	      This may be due to the device that is damaged.
Solution:     Try the previous instruction again. If it fails a second time then it
              is likely that the device needs to be replaced.
********************************************************************************

Error Name:   Flash_ProgramFailed
Description:  The value that should be programmed has not been written correctly
              to the Flash memory.
Solutions:    Make sure that the Page which is supposed to receive the value
              was erased successfully before programming. Try to erase the Page and
              to program the value again. If it fails again then the device may
              be faulty.
********************************************************************************

Error Name:   Flash_WrongType
Description:  This message appears if the Manufacturer and Device Identifications read from
              the Flash device in use do not match the expected Identification
              values. This means that the source code is not explicitly written for
              the currently used Flash chip. It may work, but correct operation is not
              guaranteed.
Solutions:    Use a different Flash chip with the target hardware or contact
              STMicroelectronics for a different source code library.
********************************************************************************

Return Name:  Flash_Success
Description:  This value indicates that the Flash memory instruction was executed
              correctly.
