Low-frequency Crystal Oscillator
The CKSEL0 Fuse together with the SUT1..0 Fuses select the start-up times as shown in
8-6.
Table 8-6.
Notes:
The Low-frequency Crystal Oscillator is optimized for use with a 32.768 kHz watch crystal.
When selecting crystals, load capacitance and crystal’s Equivalent Series Resistance, ESR
must be taken into consideration. Both values are specified by the crystal vendor. ATmega169P
oscillator is optimized for very low power consumption, and thus when selecting crystals, see
Table 8-7
Table 8-7.
Note:
The Low-frequency Crystal Oscillator provides an internal load capacitance, see
