DS80C320.H INCLUDE FILE IS INCORRECT

Applies to: C51 C Compiler

Answer

QUESTION

The 80c320 header file has the T2CON and SCON1 sbits mapped at the same address: C8--CF. The SCON1 bits should be C0--C7.

ANSWER

You are correct. There was a problem with the include file DS80C320.H that was shipped with C51 Version 5.20 and earlier. The Version 5.5 update corrects this problem. You may download the corrected version of this header file from the Keil Device Database at:
