LPSPI chip select remains in active state(low) after LPSPI_MasterTransferBlocking call.

Hi all,

I am using LPSPI5 in polling mode for communicating with one of the device on SPI.

I have configured SPI using configuration as in below picture.

As per the configuration I expect chip select line of SPI must remain in idle or non-active state(high) after LPSPI_MasterTransferBlocking  function call as all the data is transmitted/received. But chip select remains in active state (LOW), I have verified it using DSO. After power on chip select pin is high but after BOARD_InitPins function execution it remains low throughout the program.

My project is C++ project.

Please let me know what is missing in the configuration. Or anything to be verified in implementation.
