Programming the
AVR
The AVR (AT90PWM2, AT90PWM3...) can be programmed using both SPI and High-
voltage Parallel Programming. This section will explain how to connect the programming
cables to successfully use one of these two modes. The AVR Studio STK500 software
is used in the same way as for other AVR parts
Note:
The AT90PWM3 also support Self Programming, See AVR109 application note
for more information on this topic.

In-System
Programming
Figure 2-4. In-System Programming
To program the AT90PWM3 using ISP Programming mode, connect the 6-wire cable
between the ISP6PIN connector on the STK500 board and the ISP connector on the
STK520 board as shown in Figure 2-4. The device can be programmed using the Serial
Programming mode in the AVR Studio4 STK500 software.
Note:
See STK500 User Guide for information on how to use the STK500 front-end
software for ISP Programming.
