The product does not have a dedicated power supply connector. When connected to the INV-BRD it draws power via
the connector. When not connected to the INV-BRD, it can draw power via the Emulator connector. The product is not
allowed to draw power via the Emulator connector when it is connected to the INV-BRD.

Connecting the Emulator
The E1/E2 Lite on-chip debugging emulator from Renesas Electronics is used to write software (program) to the flash
memory of the RX72T. Software will be downloaded into the product via E1 or E2 Lite. It is also necessary to make the
settings shown in Table 6-1 in the integrated development environment to enable the emulator to supply power to the
product. Table 6-2 lists the pin assignments of the Emulator connector.
