for
example, a

PROMPT 48 Commands and
Functions
Access
Easy access
to
the
pins
of
the
executing
processor
is
provided via the
110
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.
1/0
ports
may be expanded, as
with
the 8243,
or
peripheral con-
trollers
may be memory-mapped. The
1/0
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
comma
ndlfunction
group panel keyboard and dis-
plays
completely
con
trol
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.
