    Use inline assembly for the EI / DI instructions, or use the intrinsic functions: This is from the help-file "Compiler-CCRL.chm" located in the folder "C:\Program Files (x86)\Renesas Electronics\CS+\CC\CC-RL\Help".

    Code-flash would have to be addressed as "far" data memory, I might recommend using the IAR compiler as it handles the "huge" memory qualifier that allows "far" array accesses across 64KB boundaries.  Or you could use CC-RL with a simple assembly routine to handle the "huge" memory references.

    Do you see the note on page 20 of the Hardware User's Manual? It says clearly that PIOR has to be used to change the function to TxD0/RxD0.
