CHAPTER 2 CONNECTION
(4) Connecting external sense clip (when external sense clip is used)
The emulation probe is provided with an external sense clip that consists of eight clips and can trace the
signals of the hardware on the target system in real time.
Because the external sense clip is directly connected to the input buffer HCT244 in the in-circuit emulator,
its input is TTL level.
Usually, the eight external sense clips are used as input signal lines. Depending on the setting of the OUT
command of the in-circuit emulator, however, the signal line of external sense clip 1 can be used to output
a trigger signal to an external device when an event occurs (for details, refer to the manual of the in-circuit
emulator).
Cautions 1.
Connect the external sense clips to the signal lines of TTL level.
If they are
connected to the other signal lines, the high and low levels of signals cannot be
accurately detected. In addition, the sensors of the in-circuit emulator may be
damaged depending on the voltage level.
2.
When using external sense clip 1 as a trigger output line, make sure that external
sense clip 1 is not connected to a signal output line. Otherwise, malfunction may
occur.
