i would like to get 48MHz core frequency and 24MHz Bus frequency in FEE Mode. But if i am using an 8 MHz crystal i just get 40 MHz and 20 MHz. Which crystal and which RDIV i need to get 48 MHz and 24 MHz? i do not think that i could find something like 9,6/9,9MHz Crystal on the market?
the OSC frequency must be in the range 31.25 kHz to 39.0625 kHz. So if i have 39.0625KHz then after FLL (x1280) i will get 50MHz on the ICS output!! But KEA128 can max. 48MHZ!!
how to solve this?
thanks in advance,
