two machine cycles or 24 oscillator cycles. Therefore,
they required the same amount of time. In the
DS87C530, the MOVX instruction takes as little as two
machine cycles or eight oscillator cycles but the “MOV
direct, direct” uses three machine cycles or 12 oscillator
cycles. While both are faster than their original counter-
parts, they now have different execution times. This is
because the DS87C530 usually uses one instruction
cycle for each instruction byte. The user concerned with
precise program timing should examine the timing of
each instruction for familiarity with the changes. Note
that a machine cycle now requires just four clocks, and
provides one ALE pulse per cycle. Many instructions
require only one cycle, but some require five. In the orig-
inal architecture, all were one or two cycles except for
MUL and DIV. Refer to the High–Speed Microcontroller
User’s Guide for details and individual instruction tim-
ing.
