S32K312 FLEXIO SPI DMA

[victory]

1.When using the S32K312 FLEXIO SPI DMA feature, the CS pin exhibits a waveform with a duty cycle of approximately 43.42%, as shown in the diagram below.

2.Help to explain the reason for the 43.42% duty cycle waveform appearing on the above-mentioned CS pin, the source code is attached.

Additionally, the SPI is able to send and receive data properly.

I suppose it is measured before SPI transmission is started i.e.once during application configuration.
From SPI slave point of view, this is not an issue, as SPI transmission is driven by CLK edges (with asserted CS).
It could be caused for instance by pull-down resistor (internal or external).
