Could help in coding for MAX11040K ADC?

Sorry but really don’t know how to do the coding for this SPI ADC.
Could someone write the part for reading the ADC?
Really thanks for that!

Same question!
It's a 4 differential channels simultaneous ADC.
32bits sampling instant control register to control each four channels
96 bits data register to read out four channels outputs.
How to send 32 bits control register through SPI, SPI.transfer can only transfer 8 bits, right? Should I do SPI.transfer four times?
What's a proper way to select the three bytes from total 12 bytes?
