    There has been a starter kit for R32C/111, but nothing for a chip in LGA package.
    Important pins for mode selection are ports P5_0 and P5_5, P6_5 and CNVss. RESET has to be released to "H" once the mode selection pins are set to flash programming mode.
    I have no idea where to buy devices in LGA. As it is difficult to solder there will never have been many distributors selling it.
