16bit communication, baud rate is 500kHz, data is transmitted with 16bit transmission function. In theory, the numbers 11120, 888, 3256, and 5680 would be transmitted repeatedly. FRDM-KW36(Slave) is also set to enable 16bit communication. Now, 16bit SPI communication bet...

I am a bit confused on who controls the SPI clock frequency coming out of SPI CLOCK pin? Is it LSPCLK? Is it the baud rate register? SPIBRR? What is PCLKCR8? SPI data capturing works with rising or falling edge of the SPI Clock? Then what is Baud rate ? If the clock frequency ...
