FLASH MEMORY VERSION  
[Precautions for flash memory serial I/O mode]  
[Precautions for flash memory serial I/O mode]  
1. 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.  
2. In the flash memory serial I/O mode, we recommend to connect pin P6OUTCUT with VCC via a resistor.  
(Refer to section 19.3.2 Examples of handling control pins in flash memory serial I/O mode.)  
3. When there is a possibility that the user reset signal becomes Llevel in the flash memory serial I/O mode, be sure  
to cut the current flow between the user reset pin and pin RESET by using a jumper switch, etc. (Refer to  
section 19.3.2 Examples of handling control pins in flash memory serial I/O mode.)  
4. Addresses FF9016 to FF9F16 (the user ROM area) are reserved for serial and parallel programmers. Therefore, be  
sure not to use this area.
