Clock rate for 8013 - haoyeshen - Aug 3 8:25:13 2006



Under 56F8013AVFE bean, there are two places to specify the clock 
frequency.

One is Oscillator Frequency default at 8MHz and another is System Clock 
which can be set to 32MHz.

I need to get 32MHz MIPS for the calculation and wondering if the 32MHz 
System Clock is good enough.

The 'Oscillator frequency' property is used to specify the main input clock frequncy for
the core (this property is fixed to 8MHz in case of selected on-chip oscillator. When you
select the external clock source you can specify the frequency of the external oscillator or
external clock). It means that the first decision what you need to do is to choose between the
clock source - Internal on-chip osc. / external clock - using property 'Clock source'. 

Then you should specify what System clock you need - using 'System clock (IP bus)' property.
You can also enable/disable the PLL using 'PLL  clock' property.
