FLASH MEMORY VERSION  
19.4 Flash memory parallel I/O mode  
19.4 Flash memory parallel I/O mode  
In the flash memory parallel I/O mode, the contents of the user ROM area and boot ROM area can be  
reprogrammed by using a dedicated parallel programmer. (See Figure 19.1.2.) About the parallel programmer  
concerned, consult its manufacturer, and for more information on using it, refer to the users manual of the  
parallel programmer.  
In the flash memory parallel I/O mode, the boot ROM area is assigned to addresses 016 to 1FFFF16 (word  
addresses).  
Note that if the boot ROM area has been reprogrammed in the flash memory parallel I/O mode, the flash  
memory serial I/O mode cannot be used. (Refer to section 19.3 Flash memory serial I/O mode.)  
Also, addresses FF9016 to FF9F16 (the user ROM area) are reserved for serial and parallel programmers. Therefore,  
besure not to use this area.
