PRODUCTION DATA.
DAISY is a serial input pin. When multiple devices are connected in daisy-chain mode, as illustrated in Figure 88, the DAISY pin of the first device in the chain is connected to GND. The DAISY pin of every subsequent device is connected to the SDO output pin of the previous device, and the SDO output of the last device in the chain goes to the SDI of the host processor. If an application uses a stand-alone device, the DAISY pin is connected to GND.
