I want to know the difference btwn the CPU clk and BUS clk. HCS908AW32 has max of 20mhz bus and cpu clk of 40 mhz. Does that mean that code will run at 40 mhz??or at bus clk of 20 mhz?? Can you give me any timing diagram links?? Ultimately which has the upper hand ? Bus or CPU clk ??
Added p/n to subject.
