Part 3 On-Chip Clock Synthesis (OCCS)
3.1 Introduction
Refer to the OCCS chapter of the
56F8300 Peripheral User Manual
for a full description of the OCCS.
The material contained here identifies the specific features of the OCCS design.
Figure 3-1
shows the
specific OCCS block diagram to reference from the OCCS chapter of the
56F8300 Peripheral User
Manual

3.2 External Clock Operation
The 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 designed to interface with a parallel-resonant crystal resonator in the frequency
range specified for the external crystal in
Table 10-15
. A recommended crystal oscillator circuit is shown
in
Figure 3-2
. Follow the crystal supplier’s recommendations when selecting a crystal, since crystal
