I'm evaluating FLEXIO as SPI using SDK v3.2.1 on a FRDM-KL27Z. Basically I'd need to solve 2 things:
- Set the CLK Polarity Active Low, not High as provided in the frdmkl27z_driver_examples_flexio_flexio_spi_int_spi_transfer_master
- Disable CS assertion by the driver. I need to set/clear the CS manually. Similar way than the output mode configuration (kSPI_SlaveSelectAsGpio) in the SPI driver.
How can I do to accomplish these points?
