NOTE:
NOTE:
NOTE:
The CGMXFC pin is required by the loop filter to filter out phase
corrections. An external filter network is connected to this pin. (See
Figure
To prevent noise problems, the filter network should be placed as close
to the CGMXFC pin as possible, with minimum routing distances and no
routing of other signals across the network.

The SIMOSCEN signal comes from the system integration module (SIM)
and enables the oscillator and PLL.
OSCSTOPENB is a bit in the CONFIG register that enables the oscillator
to continue operating during stop mode. If this bit is set, the Oscillator
continues running during stop mode. If this bit is not set (default), the
oscillator is controlled by the SIMOSCEN signal which will disable the
oscillator during stop mode.
