Programming with AVR JTAG ICE

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:

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.

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.
