External Clock
External RC Oscillator
1006F–AVR–06/07
To drive the device from an external clock source, XTAL1 should be driven as shown in
Figure 6.
Figure 6. External Clock Drive Configuration
For timing insensitive applications, the external RC configuration shown in Figure 7 can
be used. For details on how to choose R and C, see Table 29 on page 61. The external
RC oscillator is sensitive to noise from neighboring pins, and to avoid problems, PB5
(RESET) should be used as an output or reset pin, and PB4 should be used as an out-
put pin.
