ADM3491使能

TABLE 7管脚定义中给出了使用方法。就是看/RE和DE管脚的电平。

RE Receiver Output Enable. A low level enables the receiver output, RO. A high level places it in a high impedance state. If RE is high and DE is low, the device enters a low power shutdown mode.

DE Driver Output Enable. A high level enables the driver differential Output A and Output B. A low level places it in a high impedance state. If RE is high and DE is low, the device enters a low power shutdown mode.

可以将RE和DE管脚连接到MCU的GPIO引脚，通过控制拉高拉低来使能接收和发送。
