■ Adapter interface specifications
The pin outs of the adapter interface connectors mounted on the user system are shown in Tables 3.
The recommended connectors are listed in Table 4, and the pin configuration is shown in Figure 7.
When the adapter interface connector is mounted on the user system, connect the MCU to the adapter
interface connector according to the following specifications.
For the detailed method of connecting the user system and the adaptor, refer to the hardware manual
of MCU to be used.
Table 3 Adapter interface connector pin out (emulator system)
*1 : “BGMA” represents the BGM adapter.
*2 : “MCU” represents the evaluation MCU.
Note : The pin assignment of MB2146-08-E is not compatible with MB2146-09, MB2146-09A-E. Do not inter-
change these two BGM adapters with their respective target MCU. This may cause malfunction of De-
bug system.
