Preliminary
Figure 3-2 Connecting to a Crystal Oscillator
Note:
The OCCS_COHL bit must be set to 1 when a crystal oscillator is used. The reset condition on
the OCCS_COHL bit is 0. Please see the COHL bit in the Oscillator Control (OSCTL)
register, discussed in the 56F8300 Peripheral User’s Manual.
3.2.2
Ceramic Resonator (Default)
It is also possible to drive the internal oscillator with a ceramic resonator, assuming the overall
system design can tolerate the reduced signal integrity. A typical ceramic resonator circuit is shown
in Figure 3-3. Refer to the supplier’s recommendations when selecting a ceramic resonator and
associated components. The resonator and components should be mounted as near as possible to
the EXTAL and XTAL pins.

Note:
The OCCS_COHL bit must be set to 0 when a ceramic resonator is used. The reset condition
on the OCCS_COHL bit is 0. Please see the COHL bit in the Oscillator Control (OSCTL)
register, discussed in the 56F8300 Peripheral User’s Manual.
