4.5 Interfaces for Testing and Debugging

4.5.1 Logic Analyzer Interface

The connection for the logic analyzer consists of 2 parts:
• digital signals: LA1 to LA6 (CO500 - 505) 38-pin AMP Mictor connector
• analog signals: LA7 and LA8 (CO506,507) 20-pin connector
The assignment of all Logic Analyzer interface connectors can be found in
Appendix A.2.

4.5.2 Trace32 Lauterbach

The CO509 connector is used for connecting the trace module of the Trace32 BDM
debugger (produced by Lauterbach Datentechnik GmbH). The functionality of the
debugger can be expanded in this way.

4.5.3 ETK Connector

The ETK connector (CO508) is used for connecting the ETKP-1 emulator test probe
(made by ETAS GmbH & Co.KG), which is widely used in automotive engineering.
The ETKP-1 is a memory emulator for 32-bit microcontroller systems and makes it
possible to access data in the external and internal memory of the microcontroller
while the program is running. That way, variables can be controlled and adapted at
program runtime. This procedure is used, for example, in the calibration of engine
ECUs in the automobile industry.

4.5.4 MAPI-400+100 Interface

The MAPI-400+100 interface makes it possible to expand the EVB555 with extensive
and customer-specific hardware. For example, there could be signal converters and
output drivers connected to extend the EVB555 to a test sample of a control unit for
industrial use.
The interface consists of two parts.
• MAPI-400 interface
The MAPI-400 interface (CO600 - CO603) is a standard interface for 32-bit micro-
controllers made by Motorola. It makes all necessary signals, such as the address
and data bus, as well as control signals, available for the expansion of the micro-
controller system. The interface consists of four 100-pin sockets (Robinson
Nugent P50L-100-S-BS-TGF). The assignment is shown in Appendix A.1.1.
• "Port replacement unit" (PRU) connector
This connector (CO604, Robinson Nugent P50L-100-S-BS-TGF) extends the
MAPI-400 interface with signals of the port replacement unit (PRU). This means
that 64 general purpose I/O pins are again available in "external bus mode" that
are required for the bus interface at the MPC555.
