Calibrated Internal RC Oscillator
AT90PWM2/3/2B/3B
The Oscillator can operate in three different modes, each optimized for a specific frequency
range. The operating mode is selected by the fuses CKSEL3..1 as shown in
Table 7-4.
Notes:
The CKSEL0 Fuse together with the SUT1..0 Fuses select the start-up times as shown in
7-5.
Table 7-5.
Notes:
By default, the Internal RC OScillator provides an approximate 8.0 MHz clock. Though voltage
and temperature dependent, this clock can be very accurately calibrated by the user. The device
is shipped with the CKDIV8 Fuse programmed. See
more details.
