uint8_t u8fnFlashErase ( uint32_t *  pu32DataToErase)

This is the public function that allows erasure of data. It will copy u8fnFlashEraseFromRAM to RAM and execute the complete series of steps to correctly erase the sector.

Parameters:
pu32DataToErase,:Pointer to any address within the sector that shall be erased.
Returns:
u8Status: STATUS_FLASHING_TIME_OUT if timed-out before erasing, STATUS_PROGRAMMED_WRONG if PEG is not set to 1 after erasing, NOT_FLASHABLE if address are out of flash area.
uint8_t u8fnFlashWrite ( uint32_t *  pu32Source,
uint32_t *  pu32Destination,
uint16_t  u16Size 
)

This is the public function that allows flashing of data. It will copy u8fnFlashWriteDataFromRAM to RAM and execute the complete series of steps to correctly flash.

Parameters:
pu32Source,:Pointer to data source that must be flashed.
pu32Destination,:pointer to initial destination location.
u16Size,:Number of 32-bit words to be flashed.
Returns:
u8Status: STATUS_FLASHING_TIME_OUT if timed-out before flashing, STATUS_PROGRAMMED_WRONG if PEG is not set to 1 after flashing, NOT_FLASHABLE if addresses are out of flash area.
