2.2.2
In HS, HSPLL, XT and XTPLL Oscillator modes, a
crystal or ceramic resonator is connected to the OSC1
and OSC2 pins to establish oscillation. Figure 2-2
shows the pin connections.
The oscillator design requires the use of a parallel cut
crystal.

TABLE 2-1:
Capacitor values are for design guidance only.
These capacitors were tested with the resonators
listed below for basic start-up and operation. These
values are not optimized.
Different capacitor values may be required to produce
acceptable oscillator operation. The user should test
the performance of the oscillator over the expected
V
See the notes following Table 2-2 for additional
information.
When using ceramic resonators with frequencies
above 3.5 MHz, HS mode is recommended over XT
mode. HS mode may be used at any V
the controller is rated. If HS is selected, the gain of the
oscillator may overdrive the resonator. Therefore, a
series resistor should be placed between the OSC2
pin and the resonator. As a good starting point, the
recommended value of RS is 330 Ω.
