Notes: 1. To connect the signals output from the H-UDI port connector, refer to the

device pin alignment.

2. To remove the user system interface cable from the user system, pull the tab

on the connector upward.

3. The range of frequencies that the H-UDI operates at is different according to

the devices used. For details, refer to section 6.5.4, Notes on Using the JTAG

Clock (TCK) and AUD Clock (AUDCK).

4. Connect the H-UDI signals from the H-UDI port connector directly to the

device.

5. When developing user systems, do not connect the TDI and TDO signals of the

device to the boundary scan loop, or separate them by using a switch (figure
