System Overview
2.3.6
BDM Header
BDM has the ability to program either the MC9S08LG32 MCU or the MC9S08JM60 Comm MCU.
1. To choose the MC9S08LG32 MCU as a programming target, place jumpers on position 5–3 and
6–4 on J6.

When using the Electrode Graphing Tool, the communication between the MC9S08LG32 MCU and the
MC9S08JM60 Comm MCU is required. The communication is achieved through the IIC module from
each MCUs. J10 and J11 connect the IIC modules from both MCUs.
1. To connect the SCL signals of the MC9S08LG32 MCU and the MC9S08JM60 Comm MCU, place
the jumper on J10.
