Is there a document that explains clock generation in the MC9S12E128? I am using a 16MHZ Oscillator and am confused about what to expect for the bus clk, pclk, eclk, system clock. The division of the oscillator into the various clocks is what I don't understand.
 
If you have a 16MHZ oscillator, i.e, it says 16MHZ on the side of the can, is the system osc 16 or 8MHZ?
 
Thanks,
