External Clock
When this Oscillator is used as the chip clock, the Watchdog Oscillator will still be used for the
Watchdog Timer and for the Reset Time-out. For more information on the pre-programmed cali-
bration value, see the section
Table 8-9.
Notes:
When this Oscillator is selected, start-up times are determined by the SUT Fuses as shown in
Table 8-10 on page
Table 8-10.
Note:
To drive the device from an external clock source, XTAL1 should be driven as shown in
8-3 on page
to “0000”.
Figure 8-3.
When this clock source is selected, start-up times are determined by the SUT Fuses as shown in
Table 8-12 on page
