I am implementing AD7674 ADC in my application with SPI interface.
I am designing board based on SPI interface.
As per datasheet, for SPI interface below schematic is shown for reference.
But I am not able to figure what would be status of other lines used for SPI.
This pins are Pin 11(DIVSCLK0), Pin12(DIVSCLK1)Pin15(INVSCLK), D1 to D3 (8,9,10), D12 to D17 (23 to 28).
Can I put them floating?
Please someone guide. Thank you in advance.
