External Clock
Figure 4-3.
When this oscillator is selected, start-up times are determined by the SUT fuses or by CSUT
field as shown in
Table 4-8.
Notes:
To drive the device from this external clock source, CLKI should be driven as shown in
4-4. To run the device on an external clock, the CKSEL Fuses or CSEL field must be pro-
grammed as shown in
Figure 4-4.
When this clock source is selected, start-up times are determined by the SUT Fuses or CSUT
field as shown in
This external clock can be used by the asynchronous timer if the high or low frequency Crystal
