Program Status Word issue in 8051

Hi,

Progam Status Word register in MCU 8051 is not working properly. Bits P, OV, RS1 and AC are behaving incorrectly.

I am attaching the code which describes the problem in more detail.

Thanks

You are welcome.

This document could be useful in solving the problem:

See:

• Page 42 (2-11) - Program Status Word
  
• Page 52 (2-21) - Instructions that Affect Flag Settings
  
• Page 60 (2-29) - Description of the ADD function with comments on the OV, C and AC bits  
  

Good luck!

This issue is hopefully solved at Rev 1348.
