128 kHz Internal Oscillator
The 128 kHz internal Oscillator is a low power Oscillator providing a clock of 128 kHz. The fre-
quency is nominal at 3V and 25
° C. This clock may be select as the system clock by
programming the CKSEL Fuses to “0011” as shown in Table 7-12.
Note:
1. The frequency is preliminary value. Actual value is TBD.
When this clock source is selected, start-up times are determined by the SUT Fuses as shown in
7.8
External Clock
To drive the device from an external clock source, XTAL1 should be driven as shown in Figure
7-4. To run the device on an external clock, the CKSEL Fuses must be programmed to “0000”.
Figure 7-4.
External Clock Drive Configuration
When this clock source is selected, start-up times are determined by the SUT Fuses as shown in
Table 7-12.
