128 KHz Internal Oscillator
Table 4-7.
When this Oscillator is selected, start-up times are determined by the SUT Fuses or by CSUT
field as shown in
Table 4-8.
The 128KHz internal Oscillator is a low power Oscillator providing a clock of 128KHz. The fre-
quency is nominal at 5V and 25°C. This clock may be selected as the system clock by
programming 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 4-9.
