Using reserved words for SFRs with the assembler (CC-RL)

Last Updated:05/10/2017


I am using the CC-RL compiler for RL78 devices. I include the file iodefine.h in files of C source code that require access to SFRs. Is there an equivalent file for inclusion for access to SFRs from assembler code?


There is no file corresponding to iodefine.h for assembly language in CC-RL. The reserved words for SFRs can be used as they are, since the assembler of CC-RL reads the device information file.

Note that iodefine.h cannot be used with files of assembler code since it is written in the C language.
