CHAPTER 24 EXAMPLE OF F
24.4
Example of Minimum Connection with Flash Microcontroller
Programmer (When Power Supplied by User)
Figure 24.4-1 is an example of the minimum connection with the flash microcontroller
programmer when power is supplied by the user.
Serial write mode: MD2, MD1, MD0 = 110
■ Example of Minimum Connection with Flash Microcontroller Programmer
(when Power Supplied by User)
If the pins are set as shown in Figure 24.4-1 during writing to flash memory, MD2, MD1, MD0, P00 and
flash microcontroller programmer connection is unnecessary.
