在多数情况下,集成电路芯片的管脚不会全部被使用。例如74ABT16244系列器件最多可以使用16路I/O管脚,但实际上通常不会全部使用,这样就会存在悬空端子。所有数字逻辑器件的无用端子必须连接到一个高电平或低电平,以防止电流漂移(具有总线保持功能的器件无需处理不用输入管脚)。究竟上拉还是下拉由实际器件在何种方式下功耗最低确定。-in most cases, the IC chips will not pin all been used. For example, 74 ABT16244 series device can use up to 16 Road I/O pins. but usually not all use, so there will always be vacant terminal. All digital logic device useless terminals to be connected to a serial or low-level. to prevent the current drift (with the bus maintain functional devices need not deal with the importation of pins). What to draw from the drop-down or what the actual device under way to determine the minimum power consumption.

you need to be familiar with the customary and effective
ways to structure your code. Books about programming languages often cover
only the first two, or discuss usage only spottily. Maybe that’s because the first
two are in some ways easier to write about.This book addresses your need: customary and effective usage.-Prentice.Hall.Effective.Java.2nd.Edition.May.2008.3000th.Release
