TABLE 2-2:
2.9
A Phase Locked Loop (PLL) circuit is provided as an
option for users who wish to use a lower-frequency
external oscillator or to operate at 32 MHz with the
HFINTOSC. The PLL is designed for an input
frequency from 4 MHz to 12 MHz. The PLL multiplies
its input frequency by a factor of four when the PLL is
enabled. This may be useful for customers who are
concerned with EMI, due to high-frequency crystals.
Two bits control the PLL: the PLLEN bit of the
CONFIG1H Configuration register and the SPLLEN bit
of the OSCTUNE register. The PLL is enabled when
the PLLEN bit is set and it is under software control
when the PLLEN bit is cleared.
TABLE 2-3:
2.9.1
The Internal Oscillator Block can be used with the 4X
PLL associated with the External Oscillator Block to
produce a 32 MHz internal system clock source. The
following settings are required to use the 32 MHz inter-
nal clock source:
• The FOSC bits in CONFIG1H must be set to use
• The SCS bits in the OSCCON register must be
• The IRCF bits in the OSCCON register must be
• The SPLLEN bit in the OSCTUNE register must

The 4xPLL is not available for use with the internal
oscillator when the SCS bits of the OSCCON register
are set to ‘1x’. The SCS bits must be set to ‘00’ to use
the 4xPLL with the internal oscillator.
2.10
The CPU Clock Divider allows the system clock to run
at a slower speed than the Low/Full Speed USB
module clock while sharing the same clock source.
Only the oscillator defined by the settings of the FOSC
bits of the CONFIG1H Configuration register may be
used with the CPU Clock Divider. The CPU Clock
Divider is controlled by the CPUDIV bits of the
CONFIG1L Configuration register. Setting the CPUDIV
bits will set the system clock to:
• Equal the clock speed of the USB module
• Half the clock speed of the USB module
• One third the clock speed of the USB module
• One fourth the clock speed of the USB module
For more information on the CPU Clock Divider, see
Figure 2-1
Note:

and
When using the PLLEN bit of CONFIG1H,
the 4xPLL cannot be disabled by software
and the 8 MHz HFINTOSC option will no
longer be available.
