3.7.2
High-voltage
Programming
Hardware Description
It is not necessary to remove the 6-wire cable from its ISP position while running a pro-
gram in the AVR. The port pins used for ISP programming can be used for other
purposes in your program.
For High-voltage Programming, a 12V programming voltage is applied to the RESET pin
of the AVR device. All AVR devices can be programmed with High-voltage Program-
ming, 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 pro-
gramming signals are routed to the correct pins of the target device using the cables
supplied with STK500.
Table 3-3 summarizes the programming method and special considerations when using
High-voltage Programming.
