Programming the AVR

The Atmel AT90PWM81 can be programmed using both serial SPI and high-voltage parallel program-
ming. This section will explain how to connect the programming cables to successfully use one of these
two modes. The Atmel AVR Studio STK500 software is used in the same way as for other AVR parts.
Note:

Figure 2-3. Serial in-system programming.
To program the AT90PWM81 using ISP programming mode, connect the 6-wire cable between the
ISP6PIN connector on the Atmel STK500 board and the ISP connector on the Atmel STK521 board as
shown in
Studio 4 STK500 software.
