Functions
Initialization
status_t	FLEXNVM_Init (flexnvm_config_t *config)
	Initializes the global flash properties structure members.
Erasing
status_t	FLEXNVM_DflashErase (flexnvm_config_t *config, uint32_t start, uint32_t lengthInBytes, uint32_t key)
	Erases the Dflash sectors encompassed by parameters passed into function.
status_t	FLEXNVM_EraseAll (flexnvm_config_t *config, uint32_t key)
	Erases entire flexnvm.
status_t	FLEXNVM_EraseAllUnsecure (flexnvm_config_t *config, uint32_t key)
	Erases the entire flexnvm, including protected sectors.
Programming
status_t	FLEXNVM_DflashProgram (flexnvm_config_t *config, uint32_t start, uint8_t *src, uint32_t lengthInBytes)
	Programs flash with data at locations passed in through parameters.
status_t	FLEXNVM_DflashProgramSection (flexnvm_config_t *config, uint32_t start, uint8_t *src, uint32_t lengthInBytes)
	Programs flash with data at locations passed in through parameters via the Program Section command.
status_t	FLEXNVM_ProgramPartition (flexnvm_config_t *config, ftfx_partition_flexram_load_opt_t option, uint32_t eepromDataSizeCode, uint32_t flexnvmPartitionCode)
	Prepares the FlexNVM block for use as data flash, EEPROM backup, or a combination of both and initializes the FlexRAM.
Reading

	Reads the resource with data at locations passed in through parameters.
Verification
status_t	FLEXNVM_DflashVerifyErase (flexnvm_config_t *config, uint32_t start, uint32_t lengthInBytes, ftfx_margin_value_t margin)
	Verifies an erasure of the desired flash area at a specified margin level.
status_t	FLEXNVM_VerifyEraseAll (flexnvm_config_t *config, ftfx_margin_value_t margin)
	Verifies erasure of the entire flash at a specified margin level.
status_t	FLEXNVM_DflashVerifyProgram (flexnvm_config_t *config, uint32_t start, uint32_t lengthInBytes, const uint8_t *expectedData, ftfx_margin_value_t margin, uint32_t *failedAddress, uint32_t *failedData)
	Verifies programming of the desired flash area at a specified margin level.
Security
status_t	FLEXNVM_GetSecurityState (flexnvm_config_t *config, ftfx_security_state_t *state)
	Returns the security state via the pointer passed into the function.
status_t	FLEXNVM_SecurityBypass (flexnvm_config_t *config, const uint8_t *backdoorKey)
	Allows users to bypass security with a backdoor key.
FlexRAM
status_t	FLEXNVM_SetFlexramFunction (flexnvm_config_t *config, ftfx_flexram_func_opt_t option)
	Sets the FlexRAM function command.
status_t	FLEXNVM_EepromWrite (flexnvm_config_t *config, uint32_t start, uint8_t *src, uint32_t lengthInBytes)
	Programs the EEPROM with data at locations passed in through parameters.
Flash Protection Utilities
status_t	FLEXNVM_DflashSetProtection (flexnvm_config_t *config, uint8_t protectStatus)
	Sets the DFlash protection to the intended protection status.
status_t	FLEXNVM_DflashGetProtection (flexnvm_config_t *config, uint8_t *protectStatus)
	Gets the DFlash protection status.
status_t	FLEXNVM_EepromSetProtection (flexnvm_config_t *config, uint8_t protectStatus)
	Sets the EEPROM protection to the intended protection status.
status_t	FLEXNVM_EepromGetProtection (flexnvm_config_t *config, uint8_t *protectStatus)
