Recommended circuit example
The following figure shows an example of the recommended circuit of the emulator connector (on
the target system side).
Figure 23-3:
Example of Recommended Emulator Connection of V850E/PH2
Notes: 1.
Keep the pattern length to within 100 mm.
2.
Shield the DCK signal with GND.
3.
For detecting power supply to the target board. Connect to the N-Wire interface voltage.
4.
When DRST pin is high level: On-chip debug mode
When DRST pin is low level or open: Normal operation mode
DRST pin is connected to V
SS3
via an internal pull-down resistor
Cautions: 1. The DDO signal is 3.3 V output, and the input level of the DDI, DCK, DMS, and
DRST signals is TTL level.
2. A 3.3 V interface may not be supported, so a level shifter may be required by
some N-Wire type emulators. Refer to the manual of the emulator used. Note that
the IE-V850E1-CD-NW supports a 5 V interface.
