Connection of nRF21540 via SPI interface only

[backstreet.devisor]

Hello everyone!

Please tell me if I can connect nRF21540 to a microcontroller using only 4 SPI pins (SCK, MOSI, MISO, CSN) and control it completely? At the same time I want to leave MODE, RX_EN, ANT_SEL, TX_EN, PDN pins unconnected. 

Thank you.
