TMS320F28386D-Q1: How to release STE pin of SPI port between SPI transactions

Part Number: TMS320F28386D-Q1

Hi,

I don't want to configure the STE pin of SPI as GPIO and control it manually by my code. But if It was configured as SPI STE, when I continously performed several SPI transactions, this pin was always asserted. which caused the SPI communication failed. 

How to make SPI controller in C2000 to release STE pin between SPI transctions?

Thanks!

    Hi Jason,

    Since you have already configured your pin as the SPISTE pin itself, I would double check your pinmux selection and any external connections (if applicable) match accordingly.
