    sysCLOCK Phase Locked Loops (PLLs)
    The PLL clock input, from pin or routing, feeds into an input clock divider. There are three sources of feedback sig-
    nal to the feedback divider: from the CLKOP, from the clock net, or from an external pin. There is a PLL_LOCK sig-
    nal to indicate that VCO has locked on to the input clock signal. Figure 2-11 shows the sysCLOCK PLL diagram.
    The setup and hold times of the device can be improved by programming a delay in the feedback or input path of
    the PLL which will advance or delay the output clock with reference to the input clock. This delay can be either pro-
    grammed during con
    fi
    guration or can be adjusted dynamically. In dynamic mode, the PLL may lose lock after
