Connectors - TASKING iSystem Infineon TC397XE Hardware User Manual

Setting the jumper if VAREF2 is present on the device may prevent establishing a de-
bug connection or, in the worst case, can damage the Target board.
P2: Power supply configuration
Power supply of the Emulation Adapter is configured via the unshrouded 26-pin 2.54 mm
header (P2).

By default, all jumpers are set to connect user target power supply to the microcontroller resid-
ing on the Emulation Adapter. Only pins 1-2, 3-4, 5-6, 7-8, 9-10 and 11-12 must be bridged, but
for the convenience and ease of use, all jumpers are set, except for pins 25-26.
Pin 26 is the polarizer key preventing incorrect connection of the IEA-PS Power converter, when
being plugged in.
If a different power source is used (e.g., a Standalone operation), remove all jumpers and apply
3V3 or 5V to:
·
VEXT (pin 2),
·
VDDM (pin 4),
·
VAREF1 (pin 6),
Enclosed Power supply package (Power converter and Power adapter) simply plugs into the P2
header row, providing the necessary power supply for Emulation Adapter operation. LED1 indic-
ates if power is supplied to the Emulation Adapter.
Refer to the microcontroller documentation for more details about power voltage designations.

Be aware that debug and trace signals from the Emulation adapter superset device are
not connected to the target board. They are exposed only to the connectors on the
Emulation adapter.
P1: DAP
P1 connector exposes DAP debug interface.
