I have to integrate a device with 3-wire SPI (CS, SCK and S-IO pins).
I am using the Kinetis K24F chips (specifically, MK24FN1M0VDC12) and MCUX SDK v2.4.0.
What would be the recommended way to implement 3-wire SPI on the hardware and using the SDK?
- Does the SPI module support bi-directional S-IO pins?
- Is it acceptable to connect both MCU SIN and SOUT pins to the device's single S-IO pin directly?
- Does the v2.4.0 SDK support this configuration easily?
