In most cases you can utilize SPI MODE_3 instead of MODE_0 to work-around this behavior. If your SPI slave device in question requires SPI MODE_0 or MODE_2 timing, you can utilize the GPIO controlled SPI Slave Select option instead. In this case, you should use GPIO based CS for all of your slaves and not just the ones using mode 0 or 2 in order to guarantee correct CS toggling behavior. You can even use the same pin whose peripheral role is a SSEL, but use it as a GPIO instead. Loading
