AT90S8515
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.
Figure 2. Oscillator Connections
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.
