CHAPTER 18 SERIAL PROGRAMMING CONNECTION
18.1
Overview
The MB91F264B supports the serial onboard writing (Fujitsu standard) of the flash
memory. The following explains its specification.
■ Basic Configuration of the Serial Programming Connection
Fujitsu standard serial onboard writing uses the AF220/AF210/AF120/AF110 flash microcontroller
programmer by Yokogawa Digital Computer Corporation. The writing can be done by the program of the
single-chip mode operation. Figure 18.1-1 shows the basic configuration of MB91F264B serial
programming connection.
