This application note provides guidance on using the 73M1x66B FXO in multidevice applications. It shows a simple architecture for daisy chaining the devices.

When using multiple SPI devices in a design, the user may wish to share the SPI bus between these multiple devices. To allow for the sharing of CS lines between multiple 73M1x66B devices, the 73M1x66B offers a daisy-chain mode for the SPI interface. In this mode, the CS, SCLK and SDO lines for each device are shared while the SDI is "daisy-chained" from device to device.
