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 22-8 to set the OCDM0 bit to 1.
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.
