Nowadays I use the MCF52235EVB to test my project what needs the EPHY work meanwhile I nead to set the FlexCAN to 16tq baudtate at 500k.
But there is a problem, the The EPHY requires a 25-MHz crystal for its basic operation as it said in the MCF52235RM.
As a result when I use a 25-MHz crystal the EPHY can work,but the FlexCAN can not set to 16tq baudtate at 500k.
So what can I do if I want to set the FlexCAN to 16tq baudtate at 500k at the same time make sure the EPHY work?
Could I change the crystal to 8-MHz for the EPHY?
Is there a method that can make the MCF52235EVB to supply module clock separately to the EPHY and FlexCAN?
By the way why the EPHY requires a 25-MHz crystal for its basic operation? And why the clock is odd?
I think it is very hard to use for this.
