(4) Connecting external sense clip
The emulation probe is provided with 8 external sense clips which can trace hardware signals on the target
system in real time.
Since the external sense clips are directly connected to the input buffer HCT244 inside the in-circuit emulator
unit, they have TTL level inputs.
The 8 external sense clips are normally input signal lines. However, by setting the OUT command on the
in-circuit emulator, the signal line of external sense clip 1 can be used as an external trigger output signal line
in the case of an event (see the in-circuit emulator manual for details).
Cautions 1. Connect the external sense clip to a TTL level signal line only. Otherwise, it will not
detect the high level and low level accurately. Also, depending on the voltage level,
the IE-75001-R's sensor could be damaged.
2. Before using external sense clip 1 as an external trigger output, ensure that external
sense clip 1 is not connected to the signal output line, otherwise a fault may result.
