56F8357 Technical Data
Preliminary
3.2.2
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.
Ceramic Resonator (Default)
Figure 3-3 Connecting a Ceramic Resonator
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 Manual
.
3.2.3
The recommended method of connecting an external clock is given in
Figure 3-4
. The external
clock source is connected to XTAL and the EXTAL pin is grounded. When using an external clock
source, set the OCCS_COHL bit high as well.

3.3 Registers
When referring to the register definitions for the OCCS in the
56F8300 Peripheral User Manual
,
use the register definitions
without
the internal Relaxation Oscillator, since the 56F8357 does
NOT contain this oscillator.

Note: When using an external clocking source with
this configuration, the input “CLKMODE” should be
high and the COHL bit in the OSCTL register
should be set to 1.
