JTAG Connector
Figure 2-8 shows how to connect the JTAG ICE probe on the STK502 board.
Figure 2-8. Connecting JTAG ICE to the STK502
The JTAG connector is used for the ATmega169 built-in JTAG interface. The pin out of
the connector is shown in Figure 2-9 and is compliant with the pin out of the JTAG ICE
available from Atmel. Connecting a JTAG ICE to this connector allows On-chip Debug-
ging of the ATmega169.
More information about the JTAG ICE and On-chip Debugging can be found in the AVR
JTAG ICE User Guide, which is available at the Atmel web site, www.atmel.com.
