Figure 2-5. Connecting the Atmel AVR JTAGICE mkII to the Atmel STK521.
The ISP connector is used for the Atmel AT90PWM81 built-in debugWire interface. The pin out of the
connector is shown in
Table 2-4 and is compliant with the pin out of the JTAG ICE available from Atmel.
Connecting a JTAGICE mkII to this connector allows on-chip debugging of the AT90PWM81.
More information about the JTAGICE mkII and on-chip debugging can be found in the Atmel AVR
JTAGICE mkII User Guide, which is available at the Atmel web site, www.atmel.com.
Note: Remove the RESET jumper on the Atmel STK500 to work run properly JTAGICE mkII.
Note: MISO, MOSI, and SCK lines can be disconnected when the product is in debugging mode. They
can then be used for application purpose.
