Question asked by tarangjindal on Aug 8, 2018

Hello, 

we have 4 no. ADRF6516A ICs on our board. The SPI bus of these 4 ICs is interafced with the Controller device. 

There is only one SPI from the controller is used to interface the SPI bus of these 4 ADRF6516A ICs. 

so, please let us know that is this ADRF6516A IC makes SPI DOUT lpin tri stated when SPI bus is not in use? 

This will allows us to decide that we can short the DOUT for these 4-ICs or not.
