Internal Oscillator Circuit
A block diagram of the clock generation circuit is shown in figure 17. As shown in table 20, a ceramic
oscillator or crystal oscillator can be connected to OSC
1
and OSC
2
. The system oscillator can also be
operated by an external clock. See figure 18 for the layout of crystal and ceramic oscillator.
