Beware of any posting which begins "I think ..."

There are a number of other issues regarding using this FLASH as 
EEPROM replacement, related to sector and write line sizes, discussed 
in other posts on this message board.

Also, for real-time applications, remember that flash is inaccesible 
during flash erase/write (400 msec for erase - does not specify if 
this is typical or worst case).
