23.7.2.1 Step 1: Configure the MSS CCC Sub-Block

For each FIC block (FIC_0 and FIC_1) used in your design, select the clock divisors in the MSS clock configurator (MSS_CCC), as shown in the following figure.

Figure 23-25. MSS CCC FIC Clock Configuration

Note that the CLK_BASE field is non-editable. CLK_BASE frequency, as imposed by the SmartFusion 2 architecture, must be the minimum frequency of all FIC clock frequencies and is automatically computed by the MSS CCC configurator.
