Number of SPI clock cycles changes when below 1Mhz
Hi, I find that the number of SPI clock cycles change when I set the SPI clock speed below 1Mhz. When SPI Clock > 1 Mhz, the SPI clocks out 8 cycles 4 times, as expected. ( I am sending 4 bytes of data)When the SPI Clock < 1Mhz, the SPI clocks out 32...
