The AT90USB82/162 can be programmed using ISP capability of the JTAGICE (using

the connector adapter that comes with the programmer). This section explains how to

connect and use the AVR JTAG ICE.

Note:

The SPIEN fuse must be enabled in AT90USB82/162

to allow ISP operation. The

SPIEN fuse is disabled when using debugWire channel (Section “Debugging”,

page 22)

The Flash, EEPROM, 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.

Programming with STK500

Serial Programming The AT90USB82/162 can be programmed using the serial programming mode from

STK500 firmware. The software interface (In-System Programming of an external target

system) is integrated in AVR Studio®.

To program the device using ISP from STK500, connect the 6-wire cable between the

ISP6PIN connector of the STK500 board and the ISP connector of the STK526 as

shown in Figure 2-20.

See Figure 2-20 to see connection example for ISP with STK500.
