FIGURE 8-2:
8.5.1
The system clock is generated from the 96 MHz branch
using a configurable postscaler/divider to generate a
range of frequencies for the system clock multiplexer.
The output of the multiplexer is further passed through
a fixed divide-by-3 divider and the final output is used

These options are not compatible with USB operation. They may be used whenever the PLL branch is
selected and the USB module is disabled.

as the system clock. Figure 8-2 shows this logic in the
system clock sub-block. Since the source is a 96 MHz
signal, the possible system clock frequencies are listed
in Table 8-2. The available system clock options are
always the same, regardless of the setting of the
PLLDIV Configuration bits.
