I want to design a board with mcf52259 and need some advice.
The clock will be generated from an ic chip.The chip should be configed via i2c before working.
If I want to use the internal clock to boot the system,and then config the ic chip, swith the internal clock to the external clock,which clock mod should i choose?I mean the CLKMOD[1:0] and the XTAL pin.I have confused on the description of the three pin. Are they just only useful in booting sequecne?
Thanks. Best regards.
