I was surprised to learn MQX(Ver 4.2) does not support SPI Slave configuration.

Reference

There are many workarounds in the community but the information is in bits and pieces. So i decided to write this note.

I wanted to configure SPI0 Channel on MK64FX512VLQ12 board as Slave driven by interrupt in which can call MQX APIs. I have MQX Ver 4.2 installed.  My base BSP is derived from TWR-K64 board BSP given by MQX. IDE is KDS.f Reference hardware is TWR-K64 board.
