AT90S2313
XTAL1 and XTAL2 are input and output, respectively, of an inverting amplifier that can
be configured for use as an On-chip Oscillator, as shown in Figure 2. Either a quartz
crystal or a ceramic resonator may be used. To drive the device from an external clock
source, XTAL2 should be left unconnected while XTAL1 is driven, as shown in Figure 3.

Note:
Figure 3. External Clock Drive Configuration
When using the MCU Oscillator as a clock for an external device, an HC buffer should be
connected as indicated in the figure.
