Write Mode. The write mode custom clocking option has two selections, WR, and
WRL-WRH.
If you select WR, pin WR~ retains all of the normal functions. If you select
WRL-WRH mode, pin WR~ acts as WRL~, and pin WRH~ acts as byte high
enable.
Alternate Microprocessor Connections
You can connect to microcontroller signals that are not required by the support so
that you can do more advanced timing analysis. These signals might or might not
be accessible on the probe adapter board. The following paragraphs and tables
list signals that are or are not accessible on the probe adapter board.
For a list of signals required or not required for disassembly, refer to the channel
assignment tables beginning on page 3–6. Remember that these channels are
already included in a channel group. If you do connect these channels to other
signals, you should set up another channel group for them.
The following signals are on the probe adapter but are not acquired.
P5.0 through P5.15 P6.5
P3.0 through P3.4 P6.7
All probes are connected to the probe adapter. You can disconnect channel probes
not required by the support to make alternate connections. The channel assign-
ment tables in this chapter indicate channels not required for disassembly.
Remember that these channels are already included in a channel group. If you do
connect these channels to other signals, you should set up another channel group
for them.
80C167 Microcontroller Signal Names to 144 pin EIAJ QFP test clip pinout
You may want to connect to signals with other equipment, such as an oscillo-
scope, while analyzing activity in your SUT. You can connect to 80C167
microcontroller signals through the 144 pin EIAJ QFP test clip.
The pin out of the 144 pin EIAJ QFP test clip is mapped one-to-one with the pin
out of the 80C167.
