AVR Studio 中 STK500 处理熔丝位有巨大的优势：它是以功能组合让用户配置。 这种方式与小马(PnoyProg2000,SL-ISP)相比，具有以下的优势(优势是如此明显，可以用“巨大优势”来形容)：     1. 有效避免因不熟悉熔丝位让芯片锁死 (这是初学者的恶梦)     2. 不需要靠记忆与查文档，就能配置熔丝位(这也是初学者的恶梦)

操作界面如下： (注意：下图中，)。

上图的资料整理如下(该表下面有中文翻译与说明)：

应用举例：

比如我们想使用片内的RC振荡(即不需要接晶振)，可以选择选择下面三者之一：    Int. RC Osc. 8 MHz; Start-up time: 6 CK + 0 ms; [CKSEL=0100 SUT=00]    Int. RC Osc. 8 MHz; Start-up time: 6 CK + 4 ms; [CKSEL=0100 SUT=01]    Int. RC Osc. 8 MHz; Start-up time: 6 CK + 64 ms; [CKSEL=0100 SUT=10]比如我们想使用外部7.3728M晶振，可以选择选择下面三者之一：.; Start-up time: 258 CK + 4 ms; [CKSEL=1110 SUT=00]    或后面与.;.... 有关的选择。
