Max spi rates in the data sheets are cryptic.
Is there any xmc11000,1200,1300 where a 64MHz Peripheral clk can be used for something more than on a CCU4/CCU8?, if not why not just call it what it is, a CCU CLK.
A xmc1100 data sheet mention that shortest spi clk period is 62.5ns so that is equal 16MHz, so is that is the max rate for all xmc1100-1300 (xmc1400 24MHz)?
