3.1.5 JP (JP21) for switching external reset function via USB
JP21 is JP for switching the external reset function via USB. When using the RTS signal via USB as an external reset,
set JP21 to short-circuit.
3.1.6 Serial communication selector switch (SW6)
SW6 is used to select the MCU (RX651) or CPX4 for the serial port to be connected to the USB connector (CN5). For
more information, see section 3.1.12.
3.1.7 Switch for selecting enable/disable of MCU (RX651) (SW7)
The selection switch (SW7) enables/disables the control from the MCU (RX651) to CPX4. The setting of SW7 is
shown in Table 3-4. When using CPX4 SimpleMAC GUI, disable the MCU (factory default).

3.1.8 Reset switch (SW8)
The reset switch (SW8) is a push switch for system reset. Press this button (SW8) to initialize CPX4 and MCU
(RX651).
3.1.9 BOOT setting switch (SW9, SW10)
SW9 and SW10 are set to the selection switch of the BOOT method (UART/SROM/SPI). UART is a BOOT method
using UART communication, the SPI is a BOOT method using SPI communication, and SROM is a BOOT method from
SROM installed in the evaluation kit. The factory default is UART Boot. Table 3-5 shows the switching pattern of SWs.
