1 Introduction
The BDI2000 adds Background Debug Mode features to the HI-WAVE debugger environment.With
the BDI2000, you control and monitor the microcontroller solely through the stable on-chip debugging
services.You won’t waste time and target resources with a software ROM monitor, and you eliminate
the cabling problems typical of ICE’s. This combination runs even when the target system crashes
and allows developers to continue investigating the cause of the crash.
A RS232 interface with a maximum of 115 kBaud and a 10Base-T Ethernet interface is available for
the host interface.
The bdiHCI setup software is used to update the firmware and to configure the BDI2000 so it works
with the HI-WAVE debugger.
1.1 BDI2000
The BDI2000 is a processor system in a small box.It implements the interface between the BDM pins
of the target CPU and a 10Base-T Ethernet / RS232 connector.BDI2000 is powered by a MC68360,
512Kbyte RAM and a flash memory of 1024Kbyte. As a result of consistent implementation of lasted
technology, the BDI2000 is optimally prepared for further enhancements.The firmware and the pro-
grammable logic of the BDI2000 can be updated by the user with a simple Windows based configu-
ration program.The BDI2000 supports 1.8 – 5.0 Volts target systems (3.0 – 5.0 Volts target systems
with Rev. A/B).

2 Installation
2.1 Connecting the BDI2000 toTarget
The cable to the target system is a ten pin flat ribbon cable. In case where the target system has an
appropriate connector, the cable can be directly connected.The pin assignment is in accordance with
the Motorola specification.
In order to ensure reliable operation of the BDI (EMC, runtimes, etc.) the target cable length must not
exceed 20 cm (8").
For BDI MAIN / TARGET A connector signals see table on next page.

4 BKPT / DSCLK
BREAKPOINT
For normal modes, active-low input to the MCU. Signals a hardware breakpoint.
DEVELOPMENT SERIAL CLOCK
For background debug mode, serial input clock signal to the MCU.
6 FREEZE FREEZE
Active-high output from the MCU.Indicates that the MCU has acknowledged a breakpoint
and that it has entered background debug mode.
7 RESET

8 IFETCH / DSI
INSTRUCTION FETCH
For normal modes, output signal from the MCU. Indicates instruction pipeline activity.
DATA SERIAL IN
For background debug mode, serial data input signal to the MCU.
9 Vcc Target 1.8 – 5.0V:
This is the target reference voltage.It indicates that the target has power and it is also used
to create the logic-level reference for the input comparators.It also controls the output logic
levels to the target.It is normally fed from Vdd I/O on the target board.
3.0 – 5.0V with Rev. A/B :
This input to the BDI2000 is used to detect if the target is powered up.If there is a current
limiting resistor between this pin and the target Vdd, it should be 100 Ohm or less.

2.1.1 ChangingTarget ProcessorType
Before you can use the BDI2000 with an other target processor type (e.g.CPU32 <--> PPC), a new
setup has to be done (see Appendix A). During this process the target cable must be disconnected
from the target system.The BDI2000 needs to be supplied with 5 Volts via the BDI OPTION connec-
tor (Version A) or via the POWER connector (Version B). For more information see chapter 2.2.1
«External Power Supply».
To avoid data line conflicts, the BDI2000 must be disconnected from the target system while
programming the logic for an other target CPU.

2.2 Connecting the BDI2000 to Power Supply
2.2.1 External Power Supply
The BDI2000 needs to be supplied with 5Volts (max. 1A) via the BDI OPTION connector (Rev. A) or
via POWER connector (Rev. B/C).The available power supply from Abatron (option) or the enclosed
power cable can be directly connected. In order to ensure reliable operation of the BDI2000, keep
the power supply cable as short as possible.
For error-free operation, the power supply to the BDI2000 must be between 4.75V and 5.25V DC.
The maximal tolerable supply voltage is 5.25 VDC. Any higher voltage or a wrong polarity
might destroy the electronics.
Please switch on the system in the following sequence:
• 1 --> external power supply
• 2 --> target system

2.2.2 Power Supply fromTarget System
The BDI2000 needs to be supplied with 5 Volts (max.1A) via BDI MAIN target connector (Rev.A) or
via TARGET A connector (Rev. B/C).This mode can only be used when the target system runs with
5V and the pin «Vcc Target» is able to deliver a current up to 1A@5V. For pin description and layout
see chapter 2.1 «Connecting the BDI2000 toTarget».Insert the enclosed Jumper as shown in figure
below. Please ensure that the jumper is inserted correctly.
For error-free operation, the power supply to the BDI2000 must be between 4.75V and 5.25V DC.
The maximal tolerable supply voltage is 5.25 VDC. Any higher voltage or a wrong polarity
might destroy the electronics.

2.4 Connecting the BDI2000 to Host
2.4.1 Serial line communication
The host is connected to the BDI through the serial interface (COM1...COM4).The communication
cable between BDI and Host is a serial cable (RXD / TXD are crossed).There is the same connector
pinout for the BDI and for the Host side (Refer to Figure below).
