Why I cannot change the registers in AD9601 throuth SPI? I can only read them and the defaule value of register 0x14 is 0x20 which isn't same as described in datasheet.
The register default is wrong in the data sheet, and should be 0x20. You must follow a write of 0x00 to register 14 with a write of 0x01 to register FF (the device update register) to enable non-interleaved mode. I am sorry for this inconvenience.
