128 kHz Internal Oscillator
Table 6-3.
Notes:
When this oscillator is selected, start-up times are determined by the SUT Fuses as shown in
the table below.
Table 6-4.
Note:
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 “11” as shown in
Table 6-5.
When this clock source is selected, start-up times are determined by the SUT Fuses as shown in
Table
