• Simulating dual DPTR & movx for AT89S8252
    Hi! I'm simulating my program (ASM) in uVision v7.02a. When reading a byte from AT89S8252's internal EEPROM the movx instruction always uses the 1st DPTR, though the DPS is set to the 2nd DPTR. On...

    C51 7.0 supports dual DPTRs, at least in some major library routines. It also supports an extended DPTR. I'd like to be able to do both at once, to do block moves from far xdata to far xdata. It doesn...
