Name
Description
clk_in
The internal clock that comes from the main CLK_IN pin function. That function must be connected to the
pin by selecting it in the SWM block.
frg_clk
The output of the Fractional Rate Generator. The FRG and its source selection are shown in Figure 13.
fro_div
Divided output of the currently selected on-chip FRO oscillator. See Figure 15.
fro
The output of the currently selected on-chip FRO oscillator. See Figure 15.
