SPI synchronous read and write possible?

Honored Contributor II

Hi there, 


in my Quartus/NIOS-SBT 9.1SP2 the Altera SPI driver can only read _or_ write (or write _after_ read).  


Is the a reason why Altera took efforts to implement it that way? 

Because it would have been easier to just write/read synchronously and leave asynchronous ones to the implementor :confused: ... 


Is there a newer version where I can read and write at the same time? 

(I'm just asking this before I start touching the altera driver and correcting this). 





Sorry if this has already been answered before, but somehow I seem to be unable to search for threads that contain _both_ (or more) search terms, and I far keep too many false positives.
