2.6
A Phase Locked Loop (PLL) circuit is provided as an
option for users who wish to use a lower frequency
oscillator circuit or to clock the device up to its highest
rated frequency from the crystal oscillator. This may be
useful for customers who are concerned with EMI due
to high-frequency crystals or users who require higher
clock speeds from an internal oscillator.
2.6.1
The PLL can be enabled for any of the external
oscillator modes using the OSC1/OSC2 pins by either
setting the PLLCFG bit (CONFIG1H<4>), or setting the
PLLEN bit (OSCTUNE<6>). The PLL is designed for
input frequencies of 4 MHz up to 16 MHz. The PLL then
multiplies the oscillator output frequency by 4 to
produce an internal clock frequency up to 64 MHz.
Oscillator frequencies below 4 MHz should not be used
with the PLL.

Preliminary
2.6.2
The 4x frequency multiplier can be used with the
internal oscillator block to produce faster device clock
speeds than are normally possible with the internal
oscillator. When enabled, the PLL multiplies the
HFINTOSC by 4 to produce clock rates up to 64 MHz.
Unlike external clock modes, the PLL can only be
controlled through software. The PLLEN control bit of
the OSCTUNE register is used to enable or disable the
PLL operation when the HFINTOSC is used.
