Read-Only Author Drew Davis Posted 10-Sep-2003 17:31 GMT Toolset None	RE: Can I use both C51 and Cx51 for classic 51 chip Drew Davis My understanding was that the CX51 compiler generates code for the MX variant instruction set. I suppose that you could use that code on a classic 8051 if you happened not to generate any MX instructions. But I don't see the benefit to doing so; it's not as though the CX51 compiler has other extra features (as you might expect from the A51 / AX51 or BL51 / LX51 naming schemes). The documentation seems to use the notation Cx51 (or Cx51) to refer to the compilers collectively.
