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.

The pattern length must be 100 mm or less.
Shield the DCK signal by enclosing it with GND.
This pin is used to detect power to the target board. Connect the voltage of
the N-Wire interface to this pin.
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.
The FLMD0 signal is not required, but may be connected.
