VTref. 3.3V power
Vsupply. 3.3V power nTRST TARGET RESET - Active-low output signal that resets the target
Description
This is the target reference voltage. It is used to check if the target has power, to create the logic-level reference for the input comparators, and to control the output logic levels to the target. It is normally fed from VDD on the target board and must not have a series resistor.
This pin is not connected in SAM-ICE. It is reserved for compatibility with other equipment. Connect to VDD or leave open in target system.
JTAG Reset. Output from SAM-ICE to the Reset signal on the target
JTAG port. Typically connected to nTRST on the target CPU. This pin is normally pulled HIGH on the target to avoid unintentional resets when there is no connection.

GND
JTAG clock signal to target CPU. It is recommended that this pin is pulled to a defined state on the target board. Typically connected to
TCK on target CPU.
Common ground
Some targets must synchronize the JTAG inputs to internal clocks. To assist in meeting this requirement, a returned and retimed TCK can be used to dynamically control the TCK rate. SAM-ICE supports adaptive clocking which waits for TCK changes to be echoed correctly before making further changes. Connect to RTCK if available, otherwise to GND
