上表的英文翻譯說明如下：

注：以上中文是對(duì)照 ATmega16的中、英文版本數(shù)據(jù)手冊(cè)而翻譯。盡量按照了官方的中文術(shù)語。

應(yīng)用舉例：

比如我們想使用片內(nèi)的RC振蕩(即不需要接晶振)，可以選擇選擇下面三者之一：    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]比如我們想使用外部7.3728M晶振，可以選擇選擇下面三者之一：    Ext. Crystal/Resonator High Freq.; Start-up time: 258 CK + 4 ms; [CKSEL=1110 SUT=00]    或后面與Ext. Crystal/Resonator High Freq.;.... 有關(guān)的選擇。

熔絲位(Fuse)快速入門

編寫：armok / 2005-09-05 / www.OurAVR.com

 AVR Studio 中 STK500 處理熔絲位有巨大的優(yōu)勢(shì)：它是以功能組合讓用戶配置。 這種方式與小馬(PnoyProg2000,SL-ISP)相比，具有以下的優(yōu)勢(shì)(優(yōu)勢(shì)是如此明顯，可以用“巨大優(yōu)勢(shì)”來形容)：     1. 有效避免因不熟悉熔絲位讓芯片鎖死 (這是初學(xué)者的惡夢(mèng))     2. 不需要靠記憶與查文檔，就能配置熔絲位(這也是初學(xué)者的惡夢(mèng))

這是我們網(wǎng)站為何推薦使用STK500下載器的又一原因。

操作界面如下： (注意：下圖中，打勾的表示選中，代表0。沒有打勾的表示1)。

上圖的資料整理如下(該表下面有中文翻譯與說明)：
