I have a K27 based board, and i am attempting to use interrupt based SPI transfers. I have got chip select set for PCS0, and the controller is the master.
cmdData.isPcsContinuous = true;
cmdData.whichCtar = kDSPI_MasterCtar0;
cmdData.whichPcs = MASTER_PCS;
cmdData.isEndOfQueue = false;
cmdData.clearTransferCount = false;
Chip select is not being pulled down when i attempt to use interrupt based transfers. In blocking mode, transactions are good - chip select is pulled down, Serial In and Serial Out can see data, and slave responds as expected. However when i attempt interrupt mode, Chip Select does assert at all - it just stays high. I followed the K28 example - would appreciate any pointers on what i am missing.
