Intel mcs-48 Microscope & Magnifier User Manual


 
INTRODUCTION
At this point, there are two paths available
to
the designer/programmer and two types
of
design development aids provided by Intel
to
simplify the procedures. One system, called
PROMPT
48,
is a low cost development
system which supports machine language
programming and the second
is
the Intellec
Microcomputer Development System which
supports both machine and assembly langu-
ages. For those
of
you unfamiliar with the
advantages and disadvantages
of
machine
and assembly languages see
Section
1.2.
1.3.5 PROMPT 48
PROMPT
48
is a low cost design aid
consisting of:
an
8748 processor to execute
programs, control circuitry to provide debug
functions such
as
single step and break
points, a monitor program stored in
ROM,
an
EPROM programmer, and
ahexa-
decimal keyboard and display, There are
two
processor sockets on the front ofF>ROMPT
48,
one
for
programming the 8748 and one in

PROGRAMMING EXECUTION
SOCKET SOCKET
which a programmed
.8748
executes its
program while under control
of
the monitor
routine.
Use
of
PROMPT 48 involves . the following
steps:
1.
Loading
an
application program into the
PROMPT
RAM
memory via Hex keyboard
or
external terminal (TTY and RS232 interface
provided).
2.
Inserting
an
erased 8748 in the program-
ming socket and transferring the application
program
to
its internal EPROM.
3.
Transferring programmed 8748
to
execu-
tion socket where program is executed and
debugged under control
of
the monitor.
The monitor routine
allows the user to single
step this processor, examine
or
modify all
internal registers and data memory;
or
to
run
at
full speed and stop the processor at
predetermined breakpoints.
