CHAPTER 21 EXAMPLE OF MB90F562/F562B/F568 SERIAL PROGRAMMING CONNECTION
21.5 Example of Minimum Connection with Flash Microcomputer
Programmer (When Power Supplied from Programmer)
Figure 21.5-1 "Example of Minimum Connection with Flash Microcomputer
Programmer (When Power Supplied from programmer)" is an example of the
minimum connection with the flash microcomputer programmer when power is
supplied from the programmer.
Serial reprogramming mode: MD2, MD1, MD0=110B
s Example of Minimum Connection with Flash Microcomputer Programmer (When Power Supplied from
programmer)
If the MB90F562/F562B/F568 pins are set as shown in
Figure 21.5-1 "Example of Minimum
Connection with Flash Microcomputer Programmer (When Power Supplied from programmer)"
for writing data to the flash memory, MD2, MD1, MD0, and P00 and the flash microcomputer
programmer need not be connected.
