    What is the maximum SPI clock frequency that can driven either through SCB or UDB?



      I have an CY8CKIT-042 PSoC® 4 Pioneer Kit.


      I need to interface this kit with Adafruit display(which is driven from SPI). In this case, PSOC4 kit will be master and Display will be slave.


      But this Display can driven only through SPI and that too with 24MHz as input clock from Master(in this case PSOC-042).


      But after researching  through some examples and documents, came to know that maximum clock that can be driven from SCB SPI is 8MHz and from UDB SPI is 12MHz.


      Is this TRUE? Can't the SPI from CY8CKIT-042 PSoC® 4 Pioneer Kit can be driven to 24MHz? If we can drive it, can you share few examples of the configuration?
