there is my SPI timing in attachment.
The SPI timing needs to conform to the specifications detailed in the datasheet as per the write timing diagram.
Test that you are writing to the part by probing the MUXOUT pin, write to the device to change the MUXOUT from logic high to low and vice versa, you should see the MUXOUT pin changing state accordingly.
The data on DOUT should be available after you pulse LE low and apply the CLK pulses as per the write timing in figure 2.
