For High-Voltage programming a 12V programming voltage is applied to the RESET pin of the Atmel AVR device. All AVR devices can be programmed with High-Voltage programming, and the target device can be programmed while it is mounted in its socket.
Two different methods are used for High-Voltage programming: 8-pin parts use a serial programming interface, while other parts use a parallel programming interface. The programming signals are routed to the correct pins of the target device using the cables supplied with Atmel STK500.
The table below summarizes the programming method and special considerations when using High-Voltage programming.
