they required the same amount of time. In the
DS87C530/DS83C530, 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
counterparts, they now have different execution times.
This is because the DS87C530/DS83C530 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 original architecture, all were one or
two cycles except for MUL and DIV. Refer to the High–
Speed Microcontroller User’s Guide for details and indi-
vidual instruction timing.
SPECIAL FUNCTION REGISTERS
Special Function Registers (SFRs) control most special
features of the DS87C530/DS83C530. This allows the
device to incorporate new features but remain instruc-
tion set compatible with the 8051. EQUATE statements
can be used to define the new SFR to an assembler or
compiler. All SFRs contained in the standard 80C52 are
duplicated in this device. Table 2 shows the register ad-
dresses and bit locations. The High–Speed Microcon-
troller User’s Guide describes all SFRs.
