Function : flash_update
Parameter : *container : pointer to updated copy of data in RAM
*flashPageBase : pointer to start of destination flash segment
Date : 11.09.2002 / 26.11.2002
Description : erases the flash page and writes the values from the RAM save area to flash
(!!! works only in INFO flash !!!)
