3.2 Connecting to an aWire Target
The aWire interface requires only one data line in addition to VCC and GND. The 10-pin mini-squid cable should be used to connect between the Atmel JTAGICE3 target connector and the target board. Three connections are required, as described in the table below.
JTAGICE3 pins | Target pins | Mini-squid pin | aWire pinout |
---|---|---|---|
Pin 1 (TCK) | 1 | ||
Pin 2 (GND) | GND | 2 | 6 |
Pin 3 (TDO) | DATA | 3 | 1 |
Pin 4 (VTG) | VTG | 4 | 2 |
Pin 5 (TMS) | 5 | ||
Pin 6 (nSRST) | 6 | ||
Pin 7 (Not connected) | 7 | ||
Pin 8 (nTRST) | 8 | ||
Pin 9 (TDI) | 9 | ||
Pin 10 (GND) | 0 |
