MQX 3.6 and Interrupt Driven SPI

I have an application where I periodically dump a buffer of data out a SPI port.


I want to be able to write() the data without waiting around for it to complete, so I have been trying to use ISPI0: and I have made the TX buffer large enough to hold my whole message.


Will the driver turn off CS when it completes the write?


I am testing on a M52259DEMO board


All the examples end with a FLUSH command, but I do not want to wait around.
