CHAPTER 25 EXAMPLES OF MB90F362/T(S), MB90F367/T(S) SERIAL PROGRAMMING CONNECTION
25.2 Example of Serial Programming Connection (User Power
Supply Used)
Figure 25.2-1 shows an example of a serial programming connection when the user
power supply is used. The value 1 and 0 are input to mode pins MD2 and MD0 from
TAUX3 and TMODE of the AF220/AF210/AF120/AF110 programmer.
Serial reprogramming mode: MD2, MD1, MD0 = 110.
