CHAPTER 25 EXAMPLES OF MB90F362/T(S), MB90F367/T(S) SERIAL PROGRAMMING CONNECTION
25.4 Example of Minimum Connection to Flash Microcontroller
Programmer (User Power Supply Used)
Figure 25.4-1 shows an example of the minimum connection to the flash microcontroller
programmer when the user power supply is used.
Serial reprogramming mode: MD2, MD1, MD0 = 110.
■ Example of Minimum Connection to Flash Microcontroller Programmer (User power
supply used)
For a flash memory write, the MD2, MD1, MD0, P83, and P84 pins and flash microcontroller programmer
need not be connected if the pins are set as Figure 25.4-1 .
