51.7.2 10-pin JTAGICE3 Compatible Serial Wire Debug Interface
The JTAGICE3 debugger and programmer does not support the Cortex Debug Connector (10-pin) directly, hence a special pinout is needed to directly connect the SAM L10/L11 to the JTAGICE3, alternatively one can use the JTAGICE3 squid cable and manually match the signals between the JTAGICE3 and SAM L10/L11. The following figure describes how to connect a 10-pin header that support connecting the JTAGICE3 directly to the SAM L10/L11 without the need for a squid cable. This can also be used for the Atmel-ICE AVR connector port.
The JTAGICE3 squid cable or the JTACICE3 50mil cable can be used to connect the JTAGICE3 programmer and debugger to the SAM L10/L11. The figure illustrates the correct pinout for the JTAGICE3 50 mil, and details are given in the following table.
Header Signal Name | Description |
---|---|
SWDCLK | Serial wire clock pin |
SWDIO | Serial wire bidirectional data pin |
RESET | Target device reset pin, active low |
VTG | Target voltage sense, should be connected to the device VDD |
GND | Ground |
