Thus
it

Commands
and
Functions
Access
Easy access
to
the pins
of
the
executing processor
is
provided
via
the
I/O
ports
and bus
connector.
Only
the
EA
external
access,
SS
single step,
and
X1,
X2
clock
inputs are reserved
for
the
PROMPT
system.
Expansion
Program
or
data
memory may
be
expanded beyond
that
provided on-chip
or
in
the
PROMPT
system.
I/O
ports
may
be expanded, as
with the 8243, or peripheral con-
trollers
may
be memory-mapped. The
I/O
ports
and Bus
connector
allows the execution socket processor
to
be
directly
interfaced
to
prototype systems,
yet
be
con-
trolled
from
the
PROMPT
panel.
Control
The command/function
group
panel
keyboard
and
dis-
plays
completely
control
PROMPT 48—
a
teletypewriter
or
CRT
terminal
is
not
needed.
A
hyphen prompting
character
appears whenever
a
command
or function
can
be
entered.
Addresses and
data
are
shown
whenever
examining
registers
and memory. Parameters
for
com-
mands
and
functions are also
shown.
