Calibrated Internal RC Oscillator
External Clock
By default, the Internal RC Oscillator provides an approximate 8MHz clock. Though voltage
and temperature dependent, this clock can be very accurately calibrated by the user. See
Table 22-2 on page 179
device is shipped with the CKDIV8 Fuse programmed. See

This clock may be selected as the system clock by programming the CKSEL Fuses as shown
in
loads the pre-programmed calibration value into the OSCCAL Register and thereby automati-
cally calibrates the RC Oscillator. The accuracy of this calibration is shown as Factory
calibration in
By changing the OSCCAL register from SW, see

tion. The accuracy of this calibration is shown as User calibration in
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
calibration value, see the section
Table 7-6.
Note:
When this Oscillator is selected, start-up times are determined by the SUT Fuses as shown in
Table 7-7 on page
Table 7-7.
Note:
To drive the device from an external clock source, CLKI should be driven as shown in
