■ Adapter interface specifications
The pinouts of the adapter interface connectors mounted on the user system are shown in Tables 3
and 4. The recommended connectors are listed in Table 5, 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.
Table 3 Adapter interface connector pinout (emulator system)
*1 : “BGMA” represents the BGM adapter.
*2 : “MCU” represents the evaluation MCU.
Table 4 Adapter interface connector pinout (USB programmer)
*1 : “BGMA” represents the BGM adapter.
*2 : “MCU” represents the evaluation MCU.
*3 : Refer to the specifications of each of the MCUs for the serial port number that corresponds to the serial interface
for the USB programmer.
