TSSEVB Interfaces
5. Open the TSSEVB USB Bridge file using CodeWarrior Development Studio. From the
CodeWarrior main menu, select Project > Debug to compile and download the firmware into the
MC9S08JM60 Comm MCU.
3.2
IIC Interface
The MC9S08JM60 Comm MCU connects to the MC9S08LG32 MCU through the IIC protocol. The
communication between the MC9S08JM60 Comm MCU and the MC9S08LG32 MCU is needed when
you are using EGT. The MC9S08JM60 Comm MCU acts like a bridge between the MC9S08LG32 MCU
with TSS and the PC. The MC9S08JM60 Comm MCU includes the firmware that allows communication
with the MC9S08LG32 MCU. The TSSEVB board allows you to use the IIC module of the MC9S08JM60
Comm MCU for your own application. To do so, you must configure J10 and J11 jumpers from the
TSSEVB board and you can connect with the IIC module of the MC9S08JM60 Comm MCU module
through the communication header.
3.3
USB Interface
When the MC9S08JM60 Comm MCU is acting like a bridge, it communicates with the PC using the USB
protocol. The bridge program is loaded to the MC9S08JM60 Comm MCU by default, but the
MC9S08JM60 Comm MCU can be re-programmed using the OSBDM and the appropriate jumper
configuration on the TSSEVB board. The MC9S08JM60 Comm MCU uses the USB module of
MC9S08JM to achieve the communication with the PC.
3.4
SCI Interface
The MC9S08JM60 Comm MCU can communicate with MC9S08LG32 through the Serial
Communication Interface (SCI) protocol. To connect both MCUs, configure the jumpers on header J1 and
J2 respectively. The communication through SCI is not currently implemented and may be used in a future
demo application.
3.5
OSBDM MCU
An Open Source Background Debug Module (OSBDM) interface is available on TSSEVB. The OSBDM
interfaces to the MCU, which provides an interface for programming the on-chip flash. The BDM
connector provides the ability to connect a debug interface for development and accessing memory data.
The BDM has the ability to program MC9S08LG32 or the MC9S08JM60 Comm MCU on the board. This
is accomplished by setting the J6 connectors appropriately. The BDM interface can also be used for
traditional debugging. Debugging is accomplished using the CodeWarrior IDE for HCS08.
3.6
Additional BDM Connector for MC9S08LG32
The connector for an external BDM is also included in the TSSEVB board. This enables you to use an
external BDM to program MC9S08LG32. To enable the external BDM, leave the jumpers on J6 either
disconnected, or connected to the Communications MCU between 1-3 and 2-4.
