Description

APB_FREQ configuration register

Fields

APB_DECREASE_DIV_NUM

If this field’s value is grater than PCR_APB_DIV_NUM, the clk_apb will be automatically down to clk_apb_decrease only when no access is on apb-bus, and will recover to the previous frequency when a new access appears on apb-bus. Set as one within (0,1,3) to set clk_apb_decrease as div1/div2/div4(default) of clk_ahb. Note that enable this function will reduce performance. Users can set this field as zero to disable the auto-decrease-apb-freq function. By default, this function is disable.
APB_DIV_NUM

Set as one within (0,1,3) to generate clk_apb drived by clk_ahb. The clk_apb is div1(default)/div2/div4 of clk_ahb.
