Functions
void	MW_ClearCrcPeriodInterrupt (void)
	Clears the flag indicating that a CRC Scan period is done.
errFlag_t	MW_GetClearCrcDoneError (void)
	Reads and clears the flag indicating a CRC Scan of Flash is done and returns the scan result.
errFlag_t	MW_SetCrcScanInterrupts (bool useNmi, bool usePeriod, bool useDone)
	Configures the interrupt settings for the next CRC Scan of a Flash section.
errFlag_t	MW_EnableCrcScan (flashSection_t section, bool useCrc32)
	Enables a Cyclic Redundancy Check (CRC) Scan of the selected Flash section.
bool	MW_IsCrcScanBusy (void)
	Checks if a CRC Scan of a Flash section is ongoing.
void	MW_AbortCrcScan (void)
	Aborts an ongoing CRC Scan of a Flash section.
errFlag_t	MW_StartCrcManualMode (bool useCrc32)
	Starts a Cyclic Redundancy Check (CRC) Manual Mode calculation for manual data feeding.
void	MW_FeedCrcManualMode (uint8_t data)
	Feeds one byte into an ongoing CRC Manual Mode calculation.
uint32_t	MW_EndCrcManualMode (void)
	Ends a CRC Manual Mode calculation and returns the computed CRC result.

Detailed Description
