Example of recommended circuit
An example of the recommended circuit of the connector for emulator
connection (target system side) is shown below.
Figure 28-6
Example of recommended emulator connection circuit
Note
1.
The pattern length must be 100 mm or less.
2.
Shield the DCK signal by enclosing it with GND.
3.
This pin is used to detect power to the target board. Connect the voltage of
the N-Wire interface to this pin.
4.
In a system that uses only POC reset and not pin reset, some emulators
input an external reset signal as shown in
Figure 28-6
to set the
OCDM.OCDM0 bit to 1.
5.
The FLMD0 signal is not required, but may be connected.
Caution
The N-Wire emulator may not support a 5 V interface and may require a level
shifter. Refer to the user’s manual of the emulator to be used.
