2.11.1 Connecting to 2.54mm pitch 20-pole Dual-in-line Pins
Connect this product to 20-pole dual-in-line pins using the included 20-conductor standard-pitch cable.
Table 2.5 lists the connector assignments of the 20-conductor standard-pitch cable, and Figure 2.20 shows the pin
layout of the 20-conductor standard-pitch cable. Be careful not to connect the cable in a wrong direction, because it may
cause a fatal damage to the emulator and user system.

* VDD is connected for the emulator system to monitor power supply of the user system, and the emulator system does
not supply power to the user system.
* Pins XIN and XOUT are not connected. XIN is input from the oscillator board OSC-2 on the emulator, and it is not
input from an oscillator circuit on the user system. To change a system clock frequency, change the frequency of the
oscillator board OSC-2.
CAUTION
Note on Connecting the User System:
•
Take care not to attach the converter board in a wrong direction. It may cause a fatal damage to the
emulator.
