1 20e_cTI-20t_ARM Pin Converter
The 20e_cTI-20t_ARM Pin Converter is designed to attach an emula-
tor cable with a 20-pin cTI JTAG connection to a target board with 20
pin MultiICE connector.
1. Make sure the target is not powered when connecting!
2. Connect the 20 pin Male connector to your cTI emulator.
3. Connect the 20 pin Female socket to your target ARM.
WARNING
Caution should be exercised in connecting this adapter to the JTAG
emulator and the target JTAG header. Pay special attention to the
orientation and keying and pin outs. Be careful to connect with the
correct orientation. This adapter is not intended to be hot pluggable.
Unplug power from all sources prior to connect or disconnect.
