  • The whole point of all the 8051 derivatives is that they all have the same instruction set - the only differences are in the SFRs.

    Unless Cygnal has broken this, there will be no specific compiler suppport - it's just down to you to read the data sheet and find out what SFRs are involved, and what you need to do with them...
