CCS/MSP432E401Y: syscfg SPI CS config

user5196208

Part Number: MSP432E401Y

Tool/software: Code Composer Studio

Set as above to control SPI CS pin with GPIO.
It worked fine with MSP432E4 SDK 3.20.0.10.
However, after updating to 3.30.0.22 and using syscfg, the above setting disappears.
What should I do to control the SPI CS pin with GPIO?

Not solved yet
I want to control PA3, the SS pin of SSI0, on the MSP432E4 with GPIO.

In earlier versions of CCS,
.fssPinMask = SPIMSP432E4_PIN_NO_CONFIG,
This allows the PA3 to be controlled by GPIO.

However, I do not know how to select SPIMSP432E4_PIN_NO_CONFIG in the syscfg that was added to the new version of CCS.

Hello,

If you'd like to use your own GPIO to control the CS pin, you'll need to use SPI in 3-pin mode. When you do this, .fssPinMask = SPIMSP432E4_PIN_NO_CONFIG as seen in the attached screenshot.

Thanks,

Alexis
