  • You don't state which RL78 device that you are wanting to use, but first you would need a device with the IICA peripheral, as the SAU operating in "simplified IIC" mode does not support operating as a slave device.

    The code generator in CS+ (Applilet plugin) supports the IICA, I would recommend that you use this for a start.

  • I am using R5F10EGE Controller and IICA0 port is used for I2C Slave Device. Please find attached image for IIC settings.
