Note that this doesn't say anything about (in)compatibility with generic R-Car Gen3 compatible devices (hint: yaml conversion?). New features: - Slave Clock Stretch Select, - Fast Mode+ Enable, - Enhanced First Bit Setup Cycle configuration. Looks like the R-Car V3U variant can be treated as a generic R-Car Gen3 variant (lacking the new features, of course).
