open-drain与push-pull】GPIO的功能,简单说就是可以根据自己的需要去配置为输入或输出.但是在配置GPIO管脚的时候,常会见到两种形式:开漏(open-drain,漏极开路)和推..
Out_OD(Out Open Drain)是开漏输出 GPIO_Mode_Out_PP = 0x10, Out_PP(Out Push Pull)是推挽输出 GPIO_Mode_AF_OD = 0x1C, AF_OD(Atl Open Drain)是复用开漏 GPIO_Mode_AF_PP = 0x18 AF_PP(Atl Push Pull)是复用推挽 点灯使用的是推挽输出,所以复制GPIO_Mode_Out_PP,粘贴到GPIO_Mode这里来 然后...
1.比较器的输出结构 比较器的输出级主要有开路输出(包括:集电极开路(Open-Collector Outputs)、集电极/ 发射极开路(Open-Collector/Emitter Outputs)、漏极开路(Open-Drain Output))和推挽式输出 (Push-Pull Output)两种输出电路结构。 (1) 集电极开路输出:集电极开路输出比较器的电路结构如图 4.10 所示。TI 公司的...
内存有三种不同的频率指标,它们分别是核心频率、时钟频率和有效数据传输频率。核心频率即为内存Cell阵列(Memory Cell Array,即内部电容)的刷新频率,它是内存的真实运行频率;时钟频率即I/O Buffer(输入/输出缓冲)的传输频率;而有效数据传输频率就是指数据传送的频率(即等效频率)。●SDR和DDR1/2/3全系列频率...
Port Pin Input data 仅输入模式开漏输出模式(Open-Drain)此种模式没有输出高的能力。如果需要输出高,用户必须外接上拉电阻。注意此时外加引脚电压不得超过VDD+0.3V。开漏输出模式的端口结构示意图如下所示。 VDD "1" Port Pin Port latch data GND Input data 开漏输出模式 30 SH79F1612A 7.7.4 端口共享 ...

The push factors include low wages and lack of satisfactory working and living conditions. Social unrest,political conflicts and wars may also be determining causes. The pull factors,however,include academic freedom and extensive funds for research. Brain drain has negative impact on the sending ...
