回答: ad9361内循环是指将AD9361芯片内部的数据信号在SPI_CLK的上升沿发射,并在SPI_CLK的下降沿采样的过程。数据信号通过SPI_DI(或SPI_DIO)从BBP传输到AD9361,写入数据字段从BBP传输到AD9361。而SPI_DO(或SPI_DIO)则用于将返回的读取数据字段从AD9361传输到BBP。在ad9361初始化过程中,通过读取设备ID(REG_PRODUCT_ID)来判断芯片是否为AD9361,如果不符合预期的设备ID(PRODUCT_ID_9361),则会导致初始化错误并退出初始化过程。在初始化过程中,会将配置参数赋值给ad9361_phy,并进行相应的初始化操作。<em>1</em><em>2</em><em>3</em>
