2.4
A Phase Locked Loop (PLL) circuit is provided as an
option for users who want to use a lower frequency
oscillator circuit, or to clock the device up to its highest
rated frequency from a 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. For these
reasons, the HSPLL and ECPLL modes are available.
The HSPLL and ECPLL modes provide the ability to
selectively run the device at 4 times the external oscil-
lating source to produce frequencies up to 40 MHz.
The PLL is enabled by setting the PLLEN bit in the
OSCTUNE register (Register 2-1).
