Basic Configuration of Serial Programming Connection with MB90F481B/
MB90F482B/MB90F488B/MB90F489B
Fujitsu standard serial on-board writing uses the Yokogawa Digital Computer Corporation flash
microcontroller programmer. It is possible to write it by selecting either of the program that
operates by the single chip mode or the internal ROM external ROM bus mode.
Figure 24.1-1 shows the basic configuration for the example for serial programming connection.
