The MB95630H Series supports Flash memory serial on-board programming.
This section describes the configuration.

■ Basic Configuration of Serial Programming Connection

The BGM adaptor MB2146-07-E or MB2146-08-E, manufactured by Fujitsu Semiconductor
Limited, is used for serial onboard programming.
Figure 25.1-1 shows the basic configuration of serial programming connection.

The programming voltage (2.4 V to 5.5 V) is supplied from the user system.
It is shared with the GND of the Flash microcontroller programmer.
Connect it to a decoupling capacitor and then to the ground.
The RST pin is pulled up to V
The DBG pin provides 1-line UART communication with the programmer.
The serial programming mode is set if voltage is supplied to the DBG pin and
the V pin at specific timings.
