Hi, give me somebody an explanation? I simulate DS89c420 device on XTAL Freq 27MHz. After reset CPU clock is 6.75MHz and single cycle instuction's time is 148ns. I supposed 1 internal clock per 1 xtal clock. Thank you Petr
You're right - UV2 currently does not simulate DS89C420 core - default Dallas high-speed core is used instead. Also, be carefull with DPTR auto increment/decrement and swap, as this also works as on DS80C320... regards Dejan
