When this Oscillator is selected, start-up times are determined by the SUT Fuses as shown in
Note:
1. If the RSTDISBL fuse is programmed, this start-up time will be increased to
14CK + 4 ms to ensure programming mode can be entered.
2.
The device is shipped with this option selected.
6.2.3
Internal 128 kHz 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 “11” as shown in Table 6-6 below.
When this clock source is selected, start-up times are determined by the SUT Fuses as shown in
Note:
1. If the RSTDISBL fuse is programmed, this start-up time will be increased to 14CK + 4 ms to
ensure programming mode can be entered.
6.2.4
Default Clock Source
The device is shipped with CKSEL = "0010", SUT = "10", and CKDIV8 programmed. The default
clock source is therefore the internal RC oscillator running at 8.0 MHz with the longest start-up
time and an initial system clock prescale setting of 8, resulting in a 1 MHz system clock. The
default setting ensures every user can make the desired clock source setting using any available
programming interface.
6.2.5
Clock Startup Sequence
Any clock source needs a sufficient V
CC to start oscillating and a minimum number of oscillating
cycles before it can be considered stable.
