3.14.1 Debugging with AVR JTAG ICE mkII
Debugging
The AT90USB1287 can be programmed using specific the JTAG link. This sub-section will explain
how to connect and use the AVR JTAG ICE.
Note:
Figure 20. Connecting AVR JTAGICE mkII to the AT88Microbase
The Flash, EEPROM and all Fuse and Lock Bit options ISP-programmable, can be programmed
individually or with the sequential automatic programming option.
Note: See AVR Studio® on-line Help for information.
Every AT88CK109STK3 can be used for debugging with JTAG ICE MK II.
Connect the JTAG ICE mkII as shown in Figure 20, for debugging help; please refer to AVR
Studio® Help information.
When the JTAGEN fuse is disabled, the four TAP pins are normal port pins, and the TAP
controller is in reset. When the JTAGEN fuse is enabled, the input TAP signals are
internally pulled high. This enables the JTAG for Boundary-scan and programming. The
AT90USB1287 device is shipped with this fuse programmed.
