ADAS3022 SPI

Hi,
I am using ADAS3022 in one of my desings in which i plan to interface it directly with FTDI USB to SPI chip. What i would like to know about is if
the SPI in this deivce is 4/8 or 16bit.
The pdf discusses the CFG flag which is 16bit wide but not much on the SPI data
bit.

Also, does this part behaves as a SPI Master or Slave or Both?

    Hi saadali855,

    Yes the Configuration register(CFG)  is a 16bit word which  requires a 16bit data bus to write and read. Please see figure 68.SPI device communicate in full duplex mode, which mean  the device can be master-slave with single master,also support  multiple slave through selection with individual Chip Select(CS) pins.
