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:
The AT90PWM81 also supports Self Programming, see the Atmel AVR109 application note for
more information on this topic.
