Understanding the meaning and purpose of LNA_EN, RESET, SDIO, SCLK, IRQ (To MCU)

In the datasheet, it says...

This are the communication lines to the microcontroller and a pin to reset the radio.

The function of each communication line is listed in the datasheet here...

And the commands used to request data or implement a command to the radio are in section 5 of the datasheet. The en_lan pin is to enable a device or disable it.

First question, have you programmed microcontrollers before?

Second, have you worked with any type of serial communication before?

If the answer to either is no, I suggest that you start with an easier project to understand/learn the concepts.

Thanks for your reply. I have done computer programming for 10+ years, but I've not programmed a microcontroller. I have basic understanding of serial communication. I read through the datasheet on this IC. I did read through the datasheet and assumed that these were protocols that allow the MCU to communicate with the IC or visa versa and that there were specific things the MCU would tell the IC to do through these channels. I would like to understand the things that can be programmed in and how these might enhance the project.

Read the commands in section 5. That's everything that can be communicated.
