Function Tables
Table 3A. Control Input Function Table
After CLK_EN switches, the clock outputs are disabled or enabled following a rising and falling input clock edge as shown in Figure 1.
In the active mode, the state of the outputs are a function of the CLK/nCLK and PCLK/nPCLK inputs as described in Table 3B.
