Functions
uint16_t	EE_Init (void)
	Restore the pages to a known good state in case of page's status corruption after a power loss.
uint16_t	EE_ReadVariable (uint16_t VirtAddress, uint16_t *Data)
	Returns the last stored variable data, if found, which correspond to the passed virtual address.
uint16_t	EE_WriteVariable (uint16_t VirtAddress, uint16_t Data)
	Writes/upadtes variable data in EEPROM.
