SPI Driver issue on S32K341 and S32K344

Hi,

   Were are trying to communicate between S32K341 and NAND chip but no clock is getting generated. I am using LPSPI driver generated from Design Studio. We observe that Clock and Chip select are always pulled high even after calling SPI Transmit function. When I configured SCK and CS as GPIO, I am able to change its polarity from 0 to 1 and vice versa. When they are configure for LPSPI_SCK and LPSPI_CLK they remain HIGH always. Please let me know what might be the cause for this.
