pca9655e: i/o port expander, i2c, 16-凯发登录


rev. 5 (165kb)



pca9535e 通过 i2c 总线和 smbus 提供 16 位通用并行输入/输出 (gpio) 扩展。 pca9535e 包括两个 8 位配置输入或输出选项;输入、输出和极性反向(有效高电平或有效低电平运行)寄存器。通电时,所有 i/o 均默认为输入。每个 i/o 均可通过写入相应的 i/o 配置位配置为输入或输出。每个输入或输出的数据均保留在其相应输入或输出寄存器中。极性反向寄存器可用于在读取寄存器时对极性进行反向。所有寄存器均可由主系统读取。 pca9655e 提供开漏中断输出,当任何输入状态与其相应的输入端口寄存器状态不同时则会激活。该中断输出用于向主系统指示输出状态已发生改变。电源接通重置会将寄存器设置为其默认值,并启动器件状态机。 三个硬件引脚(ad0、ad1、ad2)用于配置该器件的 i2c 总线从地址。允许最多 64 个器件共享相同的 i2c 总线和 smbus。
