C51: AREGS/NOAREGS DIRECTIVE


Information in this article applies to:

  • C51 Version 5.50a
  • C51 Version 6.01

QUESTION

How do I use absolute registers and how does it improve my code, if it improves my code?

ANSWER

The AREGS control causes the compiler to use absolute register addressing for registers R0 through R7 to improve the efficiency of the generated code. The NOAREGS directive disables absolute register adressing for registers R0-R7.

MORE INFORMATION

  • Refer to AREGS in the Cx51 User's Guide.
