Data Structures
struct	MSC_ExecConfig_TypeDef

Macros
#define	EM_MSC_RUN_FROM_FLASH
	By compiling with the define EM_MSC_RUN_FROM_FLASH, the functions performing erase or write operations will remain in and execute from Flash. This is useful for targets that don't want to allocate RAM space to hold the flash functions. Without this define, code for Flash operations will be copied into RAM at startup. More...

#define	MSC_EXECCONFIG_DEFAULT

#define	MSC_PROGRAM_TIMEOUT 10000000ul
	The timeout used while waiting for the flash to become ready after a write. This number indicates the number of iterations to perform before issuing a timeout. More...

#define	MSC_RAMFUNC_DECLARATOR
	Expands to SL_RAMFUNC_DECLARATOR if EM_MSC_RUN_FROM_FLASH is undefined and to nothing if EM_MSC_RUN_FROM_FLASH is defined.

#define	MSC_RAMFUNC_DEFINITION_BEGIN
	Expands to SL_RAMFUNC_DEFINITION_BEGIN if EM_MSC_RUN_FROM_FLASH is undefined and to nothing if EM_MSC_RUN_FROM_FLASH is defined.

#define	MSC_RAMFUNC_DEFINITION_END
	Expands to SL_RAMFUNC_DEFINITION_END if EM_MSC_RUN_FROM_FLASH is undefined and to nothing if EM_MSC_RUN_FROM_FLASH is defined.

Enumerations
enum	MSC_Status_TypeDef { mscReturnOk = 0, mscReturnInvalidAddr = -1, mscReturnLocked = -2, mscReturnTimeOut = -3, mscReturnUnaligned = -4 }

Functions
void	MSC_Deinit (void)
	Disables the flash controller for writing.

MSC_RAMFUNC_DECLARATOR MSC_Status_TypeDef	MSC_ErasePage (uint32_t *startAddress)
	Erases a page in flash memory. More...

void	MSC_ExecConfigSet (MSC_ExecConfig_TypeDef *execConfig)
	Set MSC code execution configuration. More...

void	MSC_Init (void)
	Enables the flash controller for writing. More...

__STATIC_INLINE void	MSC_IntClear (uint32_t flags)
	Clear one or more pending MSC interrupts. More...

__STATIC_INLINE void	MSC_IntDisable (uint32_t flags)
	Disable one or more MSC interrupts. More...

__STATIC_INLINE void	MSC_IntEnable (uint32_t flags)
	Enable one or more MSC interrupts. More...

__STATIC_INLINE uint32_t	MSC_IntGet (void)
	Get pending MSC interrupt flags. More...

__STATIC_INLINE uint32_t	MSC_IntGetEnabled (void)
	Get enabled and pending MSC interrupt flags. Useful for handling more interrupt sources in the same interrupt handler. More...

__STATIC_INLINE void	MSC_IntSet (uint32_t flags)
	Set one or more pending MSC interrupts from SW. More...

MSC_RAMFUNC_DECLARATOR MSC_Status_TypeDef	MSC_WriteWord (uint32_t address, void const data, uint32_t numBytes)
	Writes data to flash memory. This function is interrupt safe, but slower than MSC_WriteWordFast(), which writes to flash with interrupts disabled. Write data must be aligned to words and contain a number of bytes that is divisable by four. More...
