128 KHz Internal Oscillator
Table 4-3.
Notes:
When this Oscillator is selected, start-up times are determined by the SUT Fuses or by CSUT
field as shown in
Table 4-4.
Notes:
The 128 KHz internal Oscillator is a low power Oscillator providing a clock of 128 KHz. The
frequency is nominal at 3V and 25°C. This clock may be selected as the system clock by pro-
gramming CKSEL Fuses or CSEL field as shown in
When this clock source is selected, start-up times are determined by the SUT Fuses or by
CSUT field as shown in
Table 4-5.
