Hi guys, 
I am working on a project with the FRDM-K28F board. My project requires that the each SPI frame should have 4 bytes (32 clocks) before the PCS goes high again. I have figuret out that the flexio supports 8 and 16 bits per frame (correct me if I am wrong). Does anyone know how to configure it to clock out 32bits before PCS goes high. Below is a screen shot of how it is working now (2 bytes/frame).
Thank you!
