3.3.3 External logic probe connection
When using the external logic probe, connect it to the option board connector.
For details, refer to the option board user’s manual.
3.3.4 Additional information
The IE-V850E-MC-A can perform real-time tracing of the emulation CPU bus cycle. In addition, an external logic
probe is included with the option board for the following three functions.
For details on its use, refer to the debugger user’s manual.
(1) Any eight signals can be traced in real time.
(2) Tracer start/stop is enabled using any eight signals.
(3) Break setting is enabled using any eight signals.
Cautions 1. Connect the external logic probe only to a TTL-level signal line. The high level and low level
cannot be detected correctly if connected to lines other than TTL-level signal lines. Note that
the sensor of the IE-V850E-MC-A and option board may be damaged by an excessive voltage
level.
2. When connecting the external logic probe, use a commercially available IC clip.
Procedure
(1) Turn off the power of the target system.
(2) Turn off the power of the IE-V850E-MC-A.
(3) Attach an IC clip to any device on the target system.
(4) Connect the external logic probe to the attached IC clip.
(5) Connect the GND of the external logic probe to the ground of the target system.
