TMS570LS3137: CS pin is not driven when SPI4NCS[0] is configured as SPI Mode

Part Number: TMS570LS3137
Other Parts Discussed in Thread: HALCOGEN

Hello,

I'm trying to use SPI4 to interface with an ADC chip, however upon writing of the DAT1 register using the function spiTransmitAndReceiveData() that's generated by Halcogen , I can see that the clock gets generated but the CS pin stays high, due to that the ADC does not respond. I've made sure that SPI4 is enabled in the pinmux settings.

Any advice would be greatly appreciated, Thanks
