GENERAL DESCRIPTION
1-1
AIM-Z80AE is an advanced developnent tool which provides debLg assistance
for both software and hardware via in-circuit emulation of the Z80
microprocessor. Use of the AIM-Z80AE is completely transparent to the
Target system configuration. No memory space or polrts are used and all
signals inclLrling RESET, INT, NMI, BUSRQ and WAIT are functional during
emulation.
Single step circui try allows user to execute Target instructions one at a
time
to see the exact effect of each instruction. Single step is functional
in R(lv1 as well as RAM.
Sixteen K bytes of emUlation RAM may be mapped into the Target memory space
at any desired address so that software may be developed even before Target
memory is available.
Breakpoint detect circuitry allows real time execution to proceed to any
desired point in the users program and then terminate with all registers and
status information saved so that execution may later be resumed. Real time
execution may also be terminated at any time with the Escape key. EVENT and
DELAY counters give added flexibility for viewing the exact point of
interest in the users program.
The 48 channel history module will simultaneously record any bus transaction
which the user may desire to see. Address bus, Data bus and Control signals
plus eighteen external probes which can be used to moni tor the Target
circuitry at other points are sampled by the history RAM.
