128kHz internal oscillator
The 128kHz internal Oscillator is a low power Oscillator providing a clock of 128kHz. 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 9-12.
Note:
1. Note that the 128kHz oscillator is a very low power clock source, and is not designed for high
accuracy.
When this clock source is selected, start-up times are determined by the SUT Fuses as shown in
Table 9-11.
