• Support for Dallas 80c390 Paged Addressing Mode?
    Hi, The C51 manual states that and how the Contiguous Adressing mode of the 80c390 etc. is supported. However, if I would like to use the Paged Addressing mode? This mode also uses 22 bit pointers...

  • 80C390 Programming Experience
    I'm just trying to get the DALLAS 80C390 microprocessor going, using Keil C51 compiler (V5.5). I quickly discovered some bugs in this chip. It is certainly not the Keil tools fault, it's in the silicon...
  • INIT.A51 on 80c390?
    Is it required to include init.a51 to initialize global variables in the 22bit contiguous mode on an 80c390? If I try and do this, I get a lot of undefined symbols: assembling INIT.A51... INIT...
