nrf21540 interface to 528xx

Hello Support,
I'm looking for reference schematic for the interface between nrf52840 (or similar) and the nrf21540 . Is there a simpler version than the developer kit user guide version in 21540 section? Have to trace it all out and can easily miss something.

Also is there some documentation and examples on how to write to nrf528xx USB port (not the usb/jlink on eval board) so I can configure the nrf21540 gain and some other parameters using the spi interface of the nrf52840?

I should be able to do write to nrf528xx USB port and send it out on the SPI port, right?

Thanks!

Thanks Kazi!
I'm also wondering if Nordic provides all the access to configuration of the nrf21540 in Visual Studio Connect and does all the real time TX and RX operations have examples that can be used so I don't have to figure this out myself?

Can all these configuration be included in config file for nrf52840 and then the nrf52840 configures the nrf21540 on powerup through GPIO serial port etc.? Such as "Tablet 3 MCU to FEM" in 21540 user guide. MCU would be the nrf52840 in this case.
Perhaps this is obvious, but it's not clear what real time functions Nordic provides.
Thank you!
