Getting Started
HPPCI JTAG I/O Voltage Detection
The mode of operation supported by the PCI emulator is dependent on
the connection method used for the 14-pin JTAG header on your target.
Table 1-2 shows how the target JTAG header connects for legacy and auto
detection modes.

HPUSB/USB Legacy Mode
Legacy mode is used for older targets that do not provide a target VDDIO
input for automatic voltage detection by the emulator. In this mode, the
voltage at which the JTAG signals run is set manually through the Config-
urator utility. The configurator utility provides a voltage selection setting
when configuring the target.
 HPUSB-ICE and USB-ICE emulators do not support auto voltage
detection mode.
