3.8 Using the Atmel JTAGICE3 with Atmel STK500

The Atmel STK500 starter kit can be used to house Atmel AVR devices to which the Atmel JTAGICE3 can connect through JTAG, debugWIRE, and SPI interfaces.

When connecting to a JTAG target, simply use the ATSTK500_JTAG_ADAPTER.

If you do not have an STK500 JTAG adapter available, the 10-pin "squid" cable can also be used to connect directly to the device's JTAG port on PORTC[5::2] of the STK500.

Connecting to debugWIRE and SPI targets is done using the 6-pin 100 mil adapter. When using the debugWIRE interface, be sure to remove the STK500's RESET jumper to allow the reset line to be driven as required.

Alternatively, the JTAGICE3 can be connected to any target interface using the 10-pin mini-squid cable provided.
