How this Personality Module Affects the Logic
Analyzer
Part of the display of the Logic Analyzer and the
choices that it offers are Personality Module dependent.
The PM 101 General Purpose Personality Module con
tains 2k words of ROM (Read Only Memory) which, when
read by the Logic Analyzer, provide it with a variety of
information which it needs to appropriately format dis
plays, etc. This sub-section provides information about
the ways in which the PM 101 ROM modifies the perfor
mance of the 7002.
Word Recognizer format
The General Purpose Personality Module produces the
following display format in the Word Recognizer:
DATA=nn
ADDRESS=nnnn
CO=b
C1=b
C2=b
C4=b
C5=b
EXT TRIG IN=b
where
"b" is a binary digit or "X",
"n" is a binary, hex or octal digit, or "X"
( default hex is shown), and
"X" is "Don't care".
Radix Selection. To vary the radix of "n" in the above
example, enter the Format mode by pressing the FORMAT
key and move the cursor to the Word Recognizer Address
Field. The display looks like this:
WORD RECOGNIZER ADDRESS Fl ELD
2-HEX
0 BINARY
1 OCTAL
2 HEX
indicating that if the user wishes to select an alternative
radix to the default hexadecimal, the "O" or "1" key should
be depressed.
Note: While the Data and Address field radices may be
varied by selections made in the Format mode, the Control
lines must always be binary.
Expansion Option. If the Expansion Option (Opt. 3,
Field Opt. 03) is present, the following display is defined
by the PM 101 for the Word Recognizer:
DATA=nnnn
AD=nnnnnn
C1=b
C2=b
CO=b
C4=b
CS=b
EXT TRIG I N=b
where
"b" is a binary digit or "X",
"n" is a binary, hex or octal digit or "X"
( default hex is shown), and
"X" is "Don't care".
@
C3=b
C3=b
As above, the choices for "n" are varied by selections
made in the Format mode.
Data Display format
Since the PM 101 is not specific to any particular
system, it does not include any mnemonic display
capability. The Mnemonic Mode, if selected, is the same as
the Absolute Mode and produces an identical display. In
both modes, if all radices are non-bi nary, the header in the
display field is:
LOC
ADDRESS
In the LOCation column, "000" is the oldest stored data
and "255" is the most recent. In the CONTROL column, C0
is on the right and C3 is on the left.
Radix Selection. After the FORMAT key on the 7002
Logic Analyzer is pressed and the cursor is appropriately
positioned, the display offers the following choices:
ADDRESS FIELD DISPLAY
2 HEX
0 BINARY
1 OCTAL
2 HEX
3 ASCII
indicating that if the user wishes to select an alternative
radix to the default hexadecimal, the "O", "1" or "3" key
should be depressed.
When the cursor is moved down, the display becomes:
DATA FIELD DISPLAY
2 HEX
0 BINARY
1 OCTAL
2 HEX
3 ASCII
If the user chooses anything other than a binary output
for the Address Field Display and Data Field Display
radices, and the Expansion Option is not present, the data
in the Acquisition Memory is displayed in the following
format:
ddd
nnnnnn
dddT
nnnnnn
where
"b" is a binary digit,
"n" is a binary, hex, octal, or ASCII digit
( default hex is shown),
"d" is a decimal digit, and
"T" indicates where the trigger occurred.
