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 or crystal oscillator edge as
shown in Figure 1. In the active mode, the state of the outputs are a function of the CLK, nCLK and XTAL inputs as described in Table 3B.
