I am planning to use the CMT peripheral in a K60. The ref guide states that the CMT was designed to work with a IF clock of 8 MHz and in order to get there provides 2 prescalers (primary and secondary) in case a higher bus clock is used. The 8 MHz give a 125ns resolution which is too little for my application. I would need to get something in the area of 20 ns corresponding to 50 MHz CMT clock. I also read that the bus clock can be up to 50 MHz. So is it possible to run the bus clock at 50 MHz and use the CMT with both prescalers on 1?
