Clock Options
Crystal Oscillator
XTAL1 and XTAL2 are input and output, respectively, of an inverting amplifier which can be configured for use as an on-
chip oscillator, as shown in Figure 2 and Figure 3. Either a quartz crystal or a ceramic resonator may be used.
External Clock
If the oscillator is to be used as a clock for an external device, the clock signal from XTAL2 may be routed to one HC buffer,
while reducing the load capacitor by 5 pF, as shown in Figure 3. To drive the device from an external clock source, XTAL2
should be left unconnected while XTAL1 is driven as shown in Figure 4.
