JTAG Connector
Figure 2-6. High-voltage (Parallel) Programming
The JTAG connector is intended for the ATmega128(L) that has a built-in JTAG inter-
face. The pinout of the JTAG connector is shown in Figure 2-7 and is compliant with the
pinout of the JTAG ICE available from Atmel. Connecting a JTAG ICE to this connector
allows On-chip Debugging of the ATmega128(L).
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.
