Functions
s32	EEPROM_Init (u32 mode)
	Restore the pages to a known good state in case of page's status corruption after a power loss.
s32	EEPROM_Read (u16 VirtAddress)
	Returns the last stored variable data, if found, which correspond to the passed virtual address.
s32	EEPROM_Write (u16 VirtAddress, u16 Data)
	Writes/upadtes variable data in EEPROM.
s32	EEPROM_SendDebugMessage (u32 mode)
