Configuring with SPI
The flexible interface can be configured with register settings. Using the register allows more device programmability. Table 16 shows the
required register writes to configure the AD9861 for FD, optional FD, HD20, optional HD20, HD10, optional HD10, and clone mode.
Note that for modes that use interleaved data buses, enabling 2× or 4× interpolation is required.
