■ 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 Fig-
ure 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.
