3.2 External Clock Operation
The 56F8357 system clock can be derived from an external crystal, ceramic resonator, or an
external system clock signal. To generate a reference frequency using the internal oscillator, a
reference crystal or ceramic resonator must be connected between the EXTAL and XTAL pins.
3.2.1
Crystal Oscillator
The internal oscillator is also designed to interface with a parallel-resonant crystal resonator in the
frequency range specified for the external crystal in
Table 10-13
. A recommended crystal
oscillator circuit is shown in
Figure 3-2
. Follow the crystal supplier’s recommendations when
selecting a crystal, since crystal parameters determine the component values required to provide
maximum stability and reliable start-up. The crystal and associated components should be mounted
as near as possible to the EXTAL and XTAL pins to minimize output distortion and start-up
stabilization time.
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 Manual
