How to stole/read data from an output serial port? (Sorry, I'm not a native English speaker)

I have a chip with Serial Input, Serial Output, and a Clock (used by both serials). I want to read the output with an Arduino or ESP-32.

The device I want to read is: https://statics.cirrus.com/pubs/proDatasheet/CS5460A_F5.pdf

How can I do this? I don't have too much expertise in serial communication.

Do I need anything else?

I would appreciate any help.
This device seems to communicate via SPI. Google for "serial peripheral interface" and learn how it works. You will then be able to know what to do with the information in chapter 4 of the datasheet.
