CHAPTER 25 EXAMPLES OF MB90F362/T(S), MB90F367/T(S) SERIAL PROGRAMMING CONNECTION
Even if the SIN1, SOT1, and SCK1 pins are used for the user system, the control circuit shown in the
figure below is required in the same way that it is for P83. (The /TICS signal of the flash
microcontroller programmer can be used to disconnect the user circuit during serial programming.)
Figure 25.3-2 Control Circuit
Connect the AF220/AF210/AF120/AF110 while the user power is off.
When the programming power is supplied from the AF220/AF210/AF120/AF110, be careful not to
short-circuit the user power supply.
