Internal EPROM. The support cannot acquire and disassemble data from systems
executing code in the internal EPROM.
Internal ROM: DAS/TLA Only. If the logic analyzer is set up to trigger on code
executed immediately after code in Internal ROM, the code will not be visible or
acquired.
For example, if the code is executing from 003000h and the trigger is defined as
that address, the logic analyzer will not see or acquire the sample. To acquire data
following 003000h, you can define the logic analyzer to trigger on 003001h.
8XC196NT Signal Configuration. The support requires a specific configuration for
some signals in your 8XC196NT-based system as shown in Table 1–2.

The Power Source jumper (J210 on the 8XC196NP probe adapter or J310 on
the 8XC196NT probe adapter) must be placed in the INT position if you have a
+5 V microcontroller and the probe adapter will be powered from the SUT.
If your SUT has a +3 V microcontroller or you do not want your SUT to provide
power to the probe adapter, you can use an alternate power source. If you use an
alternate power source, you must place the Power Source jumper to the EXT
position.
For more information on using an alternate power source, refer to Applying and
Removing Power in this chapter.
Figure 1–1 shows the location of the Power Source jumper, J210 or J310.
The Strobe Mode jumper (J430 on the 8XC196NP probe adapter or J331 on the
8XC196NT probe adapter) should be placed in the WR_STB position if your
SUT is configured to run in Write strobe mode or in the STD_WR if your SUT is
configured to run in Standard Write Control mode.

Connecting to a System Under Test
Before you connect to the SUT, you must connect the probes to the module.
Your SUT must also have a minimum amount of clear space surrounding the
microcontroller to accommodate the probe adapter. Refer to the Specifications
chapter in this manual for the required clearances.
The channel and clock probes shown in this chapter are for a 102/136-channel
module. The probes will look different if you are using a 96-channel module.
The general requirements and restrictions of microcontroller supports in the
information on basic operations shows the vertical dimensions of a channel or
clock probe connected to square pins on a circuit board.
Getting Started
8XC196NT Probe Adapter
To connect the logic analyzer to a SUT using the 8XC196NT probe adapter and a
high-density probe, follow these steps:
1. Turn off power to your SUT. It is not necessary to turn off the logic analyzer.
CAUTION. Static discharge can damage the microcontroller, the probe adapter,
the acquisition probes, or the module. To prevent static damage, handle all of the
above only in a static-free environment.
Always wear a grounding wrist strap or similar device while handling the
microcontroller and probe adapter.
2. To discharge your stored static electricity, touch the ground connector located
on the back of the logic analyzer. Then, touch the black foam on the
underside of the probe adapter to discharge stored static electricity from the
probe adapter.
3. Remove the microcontroller from your SUT.
4. Line up the pin 1 indicator on the microcontroller with pin 1 of the PLCC
socket on the probe adapter.
CAUTION. Failure to correctly place the microcontroller into the probe adapter
might permanently damage all electrical components once power is applied.
5. Place the microcontroller into the probe adapter as shown in Figure 1–2.

Without a Probe Adapter
You can use the acquisition probes and leadsets with a commercial test clip (or
adapter) to make connections between the logic analyzer and your SUT.
If you decide to connect the logic analyzer to your SUT without the TMS 142
probe adapter, you need to pay attention to the following restrictions:
H You can disassemble data from 8XC196 N-Series microcontrollers with 8-bit
or 16-bit wide buses operating in Standard Write Control mode.
H You can disassemble data from 8XC196 N-Series microcontrollers with an
8-bit wide bus operating in Write Strobe mode.
H Disassembled data will be incorrect if acquired from an 8XC196NT
microcontroller-based system operating in Dynamic Bus Width mode.
