1 Introduction
Debugging on the target board is a very important step in project design. This document will
describe how to debug on a target board.
The debugging interface described in this document can be used both as the in-circuit
debugging tool and the in-circuit programming tool.

4 Hardware Design
This chapter introduces the circuit of debugging interface.
As the MB95200 series has two types of flash, i.e. single flash and dual flash, there are two
types of debugging circuits corresponding to them. This chapter will introduce the two
programming circuits. Make sure to choose the correct circuit in application.
4.1 Single Flash MCU Debugging Circuit
Figure 4-1 shows the circuit diagram of the in-system debugging interface. To design the in-
system debugging interface, four pins, UVCC_EV, GND, RSTIN and DBG, are needed. (Add
pin RST_OUT if necessary).
.
Figure 4-1 Basic Connector Circuit for Single Flash MCU
Component Recommendation:
D1: VF < 0.3V when IF = 1mA. E.g. LL103A, 1SS294.
Below is a list of functions of the interface connector.
(1) J1 is a 10-pin connector, used as the circuit interface.
(2) The write voltage (VCC = 4.5V to 5.5V) is supplied from the user system. The UVCC_EV
and DBG pins control the PGM mode entry.
(3) Pin 2 of the connector connects to the GND.
(4) The debugger provides 10 V directly to the RSTX pin during flash erase/write operation.
If it is pulled high in the user system, please consider to add a low-drop diode for
separate H voltage.
(5) The DBG pin provides 1-line UART communication with the debugger. Serial write mode
can be set by providing special timing of DBG and VCC pins.
Target Board

If the MCU target needs a reset circuit, please design the reset circuit according to the
diagram below.
Figure 4-2 Debugging Connector and Reset Circuit for Single Flash MCU
Pin 4 of the connector is used to connect to the reset circuit. Please design a switch K1
between the reset circuit and the reset pin (RSTX). Make sure to cut off K1 to stop the high
voltage flowing through the reset circuit during the debugging operation. Turn on K1 to
supply the reset circuit to the target MCU when the debugging operation is over.

4.2 Dual Flash MCU Debugging Circuit
Figure 4-3 shows the circuit diagram of the in-system debugging interface. To design the in-
system debugging interface, three pins, UVCC_EV, GND and DBG, are needed. (Add pin
RST_OUT if necessary.)
Figure 4-3 Dual Flash MCU Debugging Circuit
Component Recommendation:
D1: VF < 0.3V when IF = 1mA. E.g. LL103A, 1SS294.
Below is a list of functions of the interface connector.
(1) J1 is a 10-pin connector, used as the interface of this circuit.
(2) The write voltage (VCC = 4.5V to 5.5V) is supplied from the user system. The UVCC_EV
and DBG pins control the PGM mode entry.
(3) Pin 2 of the connector connects to the GND.
(4) The DBG pin provides 1-line UART communication with the debugger. Serial write mode
can be set by providing special timing of DBG and VCC pins.
If the MCU target need a reset circuit, and please design a reset circuit as follow circuit.
Figure 4-4 In-system Debugger Interface
Pin 4 of the connector is used to connect to the reset circuit. Design a switch K1 between the
reset circuit and the reset pin (RSTX). When debugging operation is over, K1 can be
switched on to supply the reset circuit to the target MCU.

5 Debugging Operation
This chapter introduces debugging operation by F2MC-8L/8FX SOFTUNE.
5.1 Preparation before using F2MC-8L/8FX SOFTUNE
(1) Connect the BGMA to a PC
(2) Connect the EV-board to the BGMA (Note that user can only power on the MCU after
connecting the target board to the BGM adaptor)
(3) Power on the EV-board
