in the codewarrior, why do I set platform clk : sys_clk ratio = 3:1, the platform clk is 200MHz? my physical sys_clk is actual 100MHz, where to change sys_clk input in the code warrior?

in the manual reference, does the IFC module input clk equal to the paltform clk?

in the datasheet, there's a notice in the below, does the IFC module input clk equal to half of the paltform clk?:
