In KL02 SPI0 Slave Mode: In my design the SS is always low (i.e the KL02 as a SPI slave is always selected). I verify that the SPTEF bit is set before writing into the SPI0_D register. Then I ask the SPI master to clock. I can see that the clock is coming in but I don't see anything on the MISO line and the SPTEF bit is never set to 1 again. Am i missing something.
