Functions
void	EepromSpiInitialization (void)
	Initializes the SPI for the EEPROM. SPI, MISO, MOSI and SCLK are the same used for the SPIRIT1. This function can be replaced by EepromCsPinInitialization if SpiritSpiInit is called. More...
void	EepromCsPinInitialization (void)
	Initialization of the CSn pin of the EEPROM. This function is called internally by EepromCsPinInitialization. More...
void	EepromCsXnucleoPinInitialization (void)
	Initialization of the CSn pin of the EEPROM for XNUCLEO boards. More...
uint8_t	EepromStatus (void)
	Read the status register. More...
void	EepromRead (uint16_t nAddress, uint8_t cNbBytes, uint8_t *pcBuffer)
	Read a page of the EEPROM. A page size is 32 bytes. The pages are 256. Page 0 address: 0x0000 Page 1 address: 0x0020 ... Page 255 address: 0x1FE0. More...
void	EepromWrite (uint16_t nAddress, uint8_t cNbBytes, uint8_t *pcBuffer)
	Write a page of the EEPROM. A page size is 32 bytes. The pages are 256. Page 0 address: 0x0000 Page 1 address: 0x0020 ... Page 255 address: 0x1FE0 It is allowed to write only a page for each operation. If the bytes exceed the single page location, the other bytes are written at the beginning. More...
uint8_t	EepromResetSrwd (void)
	Reset the ERSR status bit. More...
uint8_t	EepromSetSrwd (void)
	Set the ERSR status bit. More...
void	EepromWriteEnable (void)
	Set the internal WEL flag to allow write operation. More...
uint8_t	SdkEvalGetHasEeprom (void)
	This function is to query if EEPROM is present or not. More...
void	SdkEvalSetHasEeprom (uint8_t eeprom)
	This function is to set if EEPROM is present or not. More...
